User questions & answers

Question:	I see there are air holes in the back, so if it is placed against a surface, won't it impede the airflow into the detector
Answer:	According to the company's website, the unit should be placed on its back (display facing upwards), on a flat surface, at breathing-level height, and away from windows, doors, air vents, etc. See https://support.airthings.com/hc/en-us/articles/115003370189-How-do-I-place-my-Home-radon-detector-to-obtain-correct-measurements- Or as their FAQ answer states: "You can just lay it flat on a table or a shelf. The air flows into the Radon chamber as usual." https://support.airthings.com/hc/en-us/articles/115001097069-Can-I-just-lay-the-unit-flat-on-its-back-side-
Question:	what is the shortest amount of time you can do a test with this device? a home inspection last only a few hours..will it have to be left over night
Answer:	Professional testers need to be used for a 48 hour test. For this home unit, it should run at least a week to be somewhat accurate. A month would be better. It will have a 20% deviation for a 48 hour test. 7 day test should be around 10% deviation and 2 months around 5%. Right now, mine has about a 30% deviation compared against professional 48 hour testers. I'm contacting support now for help. I've owned it for about 6 months.
Question:	Are we positive the readings are accurate? I have now tested the first floor of the house and am getting a reading of 7.5 pCi/l
Answer:	We have two older (15+ years) Safety Siren meters that read 2.3 & 2.4 for both long and short readings and seem stuck even after a reset/retest in our radon mitigated basement. The new Airthings 223 started a little over 2.0 and slowly dropped to 1.8. Yesterday I resealed the sump pit covers to the floor and the Airthings 223 1-day average already (
Question:	how often does the tester need to be calibrated and how much does it cost to calibrate
Answer:	My answer has nothing to do with radon concentration in the tested environment, but incorrect terminology being used on this discussion thread. Resetting the radon sensing instrumentation means system initialization to factory calibration, as the unit is not user calibrate able. Calibration implied by this question is to a standard, and it must have been done with the prototype designs when tested against known radon concentrations in chambers...using perhaps master instrumentation. I think this device can give you values within some level of confidence like 95%...but the measure value of any unit like this is not to be taken with 100% confidence.

By pressing the Peak Level Button you can see the peak CO level recorded by the alarm since it was last reset or unplugged. The continuous digital display shows you the level of carbon monoxide (if any) the unit is sensing as well as if gas is present. The gas sensor is a metal oxide sensor designed to detect natural gas (methane) or propane. Temperature range- 40 degree Fahrenheit to 100 degree Fahrenheit.

Protect your family from the dangers of carbon monoxide (CO), methane, and propane exposure with the Kidde KN-COEG-3 Nighthawk Plug-In Carbon Monoxide and Explosive Gas Alarm. The Nighthawk is an easy-to-install unit that provides reliable protection against the dangers of CO and explosive gas. The digital display shows if gas is present indicates CO levels in parts per million, allowing you to see if, how, and when levels change.

Advanced Technology in an Easy-to-Install, Plug-In Design

Designed for home use, the Kidde KN-COEG-3 Nighthawk is a UL-listed, A/C-powered, plug-in alarm that utilizes sophisticated electronic components and sensor technology to protect you and your family from the dangers of CO, methane, and propane exposure. It plugs directly into a standard A/C outlet and includes a 9-volt battery backup that provides continuous monitoring--even during power outages.

The Dangers of Carbon Monoxide, Methane, and Propane Exposure

The leading cause of accidental poisoning deaths in North America, carbon monoxide (CO) is often referred to as the silent killer because it's odorless, tasteless, and invisible. Carbon monoxide poisoning can come about via a number of sources, including everyday items and appliances in your home or office. And because symptoms of CO poisoning mimic the flu or other common illnesses it can often go undiagnosed.

Likewise, methane and propane gases are commonly used in homes for cooking, heating, and water heating. Although it happens rarely, gas leaks can sometimes occur inside the home, increasing the risk of fire or explosion.

Audible Alarm Pattern Alerts you to Elevated CO and Gas Levels

When placed on every level of your home, alarms like the KN-COEG-3 Nighthawk can help protect everyone in the house by giving you an unmistakable signal when gas levels have reached an unhealthy point. If unhealthy levels of CO are detected, the alarm will emit four quick audible beeps every five seconds until either levels decrease or the reset button is pressed. If methane gas or propane gas is detected, the alarm will emit beeps every other second with "GAS" shown in the display.

Easy-to-Read Digital Display Shows CO Levels

The KN-COEG-3 Nighthawk is preferred among traditional CO and explosive gas alarms because of its digital display. This display clearly shows levels of CO that the unit has detected and stored-- from 30 to 999 ppm--and it updates every 15 seconds to indicate any abrupt changes or alarming trends. The display also shows the peak CO level recorded by the alarm since it was last reset or unplugged. The continuous display also shows if gas is present.

LED Shows Sensor Status

With the KN-COEG-3 Nighthawk, you never have to wonder if the sensor is functioning properly. A blinking dot in the lower right-hand corner of the display denotes normal operation, so you can trust that it's working. In addition, you can test alarm function by pressing the test/reset button at any time to verify that the horn and electric circuitry are operating properly.

Convenient Mounting Options

The KN-COEG-3 Nighthawk has a low-profile design that makes it suitable for any room in your home. The detector can be plugged into any standard A/C outlet; it's plug can be snapped into the back of the unit and can be rotated so the alarm remains vertical, independent of whether the electrical socket is mounted vertically or horizontally. In addition, the alarm comes with a 6-foot extension cord, so the unit can be plugged into the wall outlet and then placed on a table or shelf. For the most thorough protection, place an alarm on every level of your home.

The UL-listed Kidde KN-COEG-3 Nighthawk has a seven-year life and is backed by a five-year limited warranty.

User questions & answers

Question:	What is the sound level I need one for basement and need to hear on ground floor
Answer:	Dear cutomer, excuse that this prodcut Y301 can't detect hydrogen gas, it's mainly sensitive for methane and propane. thank you very much
Question:	is this an explosive gas and carbon monoxide detector? it only says "carbon monoxide detector" on the actual product
Answer:	Don't worry, it's normal, the large moisture change can affect the sensor performance, and may lead to false alarm, but the data on display only switch to 1,2 or 3, but won;t trigger the voice and light alarm. If the data become 5 or more than 5, voice and light alarm will be triggered. Thank you very much and best regards.
Question:	No manual included. Do I just plug it in and test it? What does it display if gas is detected? Thanks fellow Amazoners
Answer:	HI Niran, it's sensitive to methane and propane. We think it can't used to monitor and detect CO. thank you vey much
Question:	I smell natural gas in my house, and am wondering if that is the same as explosive gas? Will it detect natural gas
Answer:	Dear Karen, temporarily the Y301 doesn't get UL certification, it passed CE, FCC, EMC and RoHs. We are applying US ETL certification which is equivalent to UL certification. Thank you very much and best regards.

User questions & answers

Question:	Would this device work in a 6' x 6' hunting blind with a Mr. Heater heating unit
Answer:	Not for sure but wife read that rhey can fluxiate between 0-3 with no problems mine does it also
Question:	your cob b lcm coc allarm is 15$ 6 is 99$ . why does quantity coct more
Answer:	When I used the digital gas detector to test it worked fine.
Question:	How far apart are the mounting holes
Answer:	There are two possible causes. The unit was not zeroed out upon activation or you do have a very low level of gas in your home atmosphere, with the first being my best guess. Unplug and move and re-check the reading. If this does not resolve the issue send it back for a new one. Mine has worked well for 6 months so far.
Question:	Why is the 2 pack more than 2 times the price of the single detector
Answer:	I returned these detectors. They don't have any information printed on the case - no manufacturer name, no instructions, no UL approved indicator, etc. These were made in China which is usually okay but I am not comfortable in relying on them to protect my family. I will be researching further and looking for better detectors that can be trusted.

Product description

The First Alert SCO5CN Combination Smoke and Carbon Monoxide Alarm features dual sensors to detect both smoke and carbon monoxide in a single device. A photoelectric sensor detects the smoke most often produced by smoldering fires, and minimizes false alarms from cooking smoke or shower steam. Additionally, the advanced electrochemical CO sensor detects carbon monoxide leaks from multiple sources, such as faulty fuel burning appliances, blocked chimneys, and generators running inside or too close to homes. A loud, 85 decibel siren alerts you to the threat; unique alarm sounds and indicator lights on its face distinguish a smoke warning from a carbon monoxide warning. This carbon monoxide and smoke detector is battery operated, so you don't need an electrician for installation. Requiring just two AA batteries and featuring an easy access battery compartment for quick changes, this smoke and carbon monoxide detector has a single button that allows you to silence a false alarm or test the unit.

Carbon monoxide (CO) is the leading cause of accidental poisoning deaths in America, yet many people don't know they are suffering from CO poisoning until its too late. Since symptoms of CO poisoning are like the flu, you might not even know you're in danger at first. That's why a carbon monoxide alarm is an excellent way to protect your family. It can detect the CO you can't see, smell or taste in the air.

The First Alert SCO5CN carbon monoxide and smoke alarm uses an electrochemical carbon monoxide sensor-the most accurate technology available. The alarm uses photoelectric smoke sensing technology which is environmentally friendlier and which reduces nuisance alarms, making it ideal for cooking areas. It is also great for sensing slow smoldering fires quickly. The permanent sensors last the lifetime of the alarm. The test/silence button both silences a non-threatening alarm or low battery warning and allows you to test the unit's functionality. A low battery signal alerts you to replace the battery and end-of-life alarm of three chirps alerts you to replace the unit. Two AA batteries are included. 5-year limited warranty. UL listed. Not available for sale in Massachusetts.--Bree Norlander

User questions & answers

Question:	pack is $30, 2 pack is $90. Why is a two pack so much? I thought the idea was to incentivize more product at a lower cost. This is halarious
Answer:	I no longer live in the apartment where I replaced the old smoke alarm, but you will love this one. It's so nice to flip the battery holder down and not have to remove the battery from the unit.
Question:	Advice on false alarms? Goes off every week or so. It's in our kitchen/living room, but goes off even when we are not cooking. Goes 1 min then stops
Answer:	No
Question:	I have these througout my house and rental unit. Installed them about 7 years ago and many malfunctioning. Any durability mprovments since 7 yrs ago
Answer:	The instructions that come with the unit duplicate what I have read from several Fire Department sources: you can place your unit on the ceiling, but AT LEAST 4 inches (10cm) from the wall. If you want to mount it on the wall, mount it MORE THAN 4 inches (10cm) BELOW the ceiling, but NO LOWER than12 inches (30cm) below the ceiling. It has to be high enough up the wall to "smell" the smoke, but that 4 x 4 inch (10cm x 10cm) area where the wall meets the ceiling can sometimes harbor a "dead zone" of still air where the smoke would NOT reach the detector quickly enough during a fire to warn you in time. Thus, do NOT mount your detectors too close to where the wall meets the ceiling.
Question:	How long do batteries last
Answer:	Ionization type. I actually looked at at manual to be certain.

User questions & answers

Question:	When I unplug this device the green light goes off even though the batteries are installed as a backup. Is that normal
Answer:	It's about 5 1/2 in from hinge to hinge ~ 14.5 cm. It does provide full cover. The foam is flush with my face without being uncomfortable. It however is not waterproof. The foam has air slots so it can breathe. I've used these for Chemistry lab as well as wood working, and they work great.
Question:	When I try put battery in or plug it in, the alarm goes off! Does that alarm sound stop? It's brand new
Answer:	They stay on surprisingly well! I use them for my dog grooming business. They are light weight so that works good for me. They might be a bit too light for sports. If you got hit with a ball they would probably crack and potentially cut you.
Question:	How do you turn on the "low battery hush
Answer:	Yes, it should do a good job to keep out drywall dust. However, I ended up removing it due to condensation buildup while using it
Question:	What is the location of the wall plug on the device? Will it cover the entire outlet
Answer:	yes they can fit over Rx glasses but I don't recommend because they became blurring and you will not see very well

Question:	Where do I get one for home to detect natural gas leak. Must be battery operated as have no 120v outlets near ceiling
Answer:	Yes it works fine
Question:	Is this a us style plug
Answer:	No, this only detects gas. Check out the 70-742 KIT. (Must get the kit. The kit has the valve). This has a valve and detector. It will turn off the gas if the sensor detects a leak.
Question:	What is the operating temperature range of the gas detector? Can it work normally in cold places
Answer:	No it is not. The MTI SA-8 is 6.5 inches wide x 3.5 inches tall x 1.25 inches in depth. This unit is 12 inches wide x 8 inches tall x 4 inches in depth.
Question:	should i be alarmed if the detector starts to beep at 3 then go to 4 and continue to beep at
Answer:	Of course, you can. This uint certainly won't know the difference between a kitchen in an RV, or a home! As long as you supply it with the appropriate power source 12v..it will be fine.

User questions & answers

Question:	is it precise
Answer:	Yes ours came with the headgear
Question:	Is any detection of gas harmful? My apartment supposedly just fixed its gas leak, but this is still showing the first level red light within my apt
Answer:	Don't know the max size. I wear a 7 3/4 hat and this fit fine. There is a minimal amount of adjustment left.
Question:	Do I need to replace the sensor after 2 years to keep this working? Or, is the unit useless after about 2 years? I read the sensor tip has a lifespan
Answer:	These type of hard hats is varies but it is fiberglass though. The color can be light to mid dark brown. They ship me with a light brown one. I was surprised it was very light, it was thin. Just be careful when buying from Warehouses. They say they will give you a new ratchet suspension but they never did. So be aware of that and if it happen they won't ship you a new one, they will ask you to reship it back and buy a new one, hopping you will receive the hard hat with the suspension but NO GUARENTEE. But to answer your question, yes it does look like that, but remember it varies on the seller because it come from a warehouse.
Question:	I don’t understand after it warms up how to detect gas ? Do I move the button until it stops ticking and no alarm? I move + and alarms sounds
Answer:	Front brim, ball cap style.

Techamor Portable Gas Leak Detector/Sniffer - Y201

The Y201 portable sniffer is an easy-to-use device that provides sound and visual alarm in presence of methane, propane, such as LPG, fuel and natural gas.

It’s mainly used to find and locate exact gas leak point along gas pipeline, around fittings or connectors at home & VR, and other similar applications. Helps to save hundreds of diagnostic fees from technician or plumber, and makes it's possible to debug gas leakage anytime by DIY.

For 24h gas monitor and detection, refer to Y301 and Y302.

2.1 Warm up process: around 10s

The speaker will always have “di didi…” until we turn off device, except one moment in step 2.2. At warm up period, ticking noise frequency is slow: around 2~3 times/s.

The knob is used to adjust sensitivity of detector after finish 10s warm up process, during the process, no matter how to adjust the knob, the device won't have any reactions.

2.2 Rotate the knob to adjust sensitivity

If the alarm sounds prematurely and LED lights are on after warm up, need to decrease sensitivity to prevent false alarm (dial downward "-", shown as red arrow) .

Rotate the knob to adjust sensitivity until the first bottom LED turn off or at the threshold of lighting up, and the moment that ticking sound stops. This is the best status.

But if it's inconvenient to get the best status, we can just make the first bottom LED be on and have slow ticking "di di...." sound. Because once encounter leakage, all the rest 4~5 LED will be triggered on together at just one moment.

2.3 Ready to sniff or trace leakage

Move the probe along pipeline or around the suspected leakage points, such as fittings, connectors and switches, once encounter gas leakage, all 5~6 LED lights will be triggered immediately and the low frequency (2~3 times/s) ticking will change into piercing sounds (frequency 6~7 times/s, too fast and human ears cannot distinguish one time by one time) .

3. Different Usage Pictures Collection from Lovely Customers

4.1 Could tell more related to use?

1) Easy to understand video will be good choice, refer to “How and where to use the Y201 gas leak detector” around pictures area at beginning . 2) Get service support, engineers on staff from factory online will help to answer any questions related to leakage if above video can't help to understand.

4.2 Why always has ticking sound?

The design of ticking sound has two purposes: 1) Indicates the device is working.For some cases, we need to extend the probe to the area that we can't see LED lights, customers could judge thru the sound changes. The green power LED light is also used to indicate the device is working. 2) Represent different levels of gas leakage. Low frequency (around 2~3 times/s) means warm-up period or no leakage, if changed into high frequency (around 6~7 times/s) during detection process, means encounter leakage issue.

Notes: above is based on we set sensitivity well, because if we rotate the knob at anti-clockside too much, even there don’t have any leakage, all the 6 LED will be triggered on and sound will become piecing high frequency.

4.3 Some batteries only use 10~15 minutes, then low battery indicator is on.

According to our experiment data at lab for different batteries brand, usually last from 15 minutes to 4 hours. Different brand batteries have very different quality. Indeed, the device is hungry for batteries. The sensor in the probe needs large power for micro burning process and we can feel a little warm if we use finger to hold the probe. Another reason maybe product itself, components (resistor, capacitor......) tolerance or damage on the PCB board may also lead to large power consumption, but the rate is very low.

Usually when we find customers from home inspection company, we will suggest purchasing rechargeable Li-batteries, because their technicians or plumbers use the device frequently and Li-batteries will help to save some batteries cost.

4.4 Is it normal or safe if get 1 red bar when move to high moisture room, around connectors or simply blow on probe?

Don't worry, it's normal, the large moisture change and CO affect the sensor performance, and may lead to false alarm by 1~2 LED red bars, but only last for 1~3s (very short time) if we move probe away. If we encounter leakage along the pipeline or connectors, all 5~6 LED bars will be triggered on at one moment, light and piercing sound alarm will last at least for 6~8s.

4.5 what's best distance between probe and pipeline/ranges/connectors.... during check process?

Recommend 1~10cm, if too far, concentration will become smaller as distance increase from leak point, and maybe not enough find and locate tiny leakage.

4.6 How about bubble method to check leakage compared with Y201?

Bubble is very good way and can be used to check all kinds of gas leakage while Y201 is mainly used for combustible gas. But for very tiny leakage and very strong leakage, bubble method maybe not good enough: 1) too tiny leak can't blow up bubble, too strong will blow the liquid away and can't have bubble, 2) some areas we can't extend to apply bubble liquid, 3) need good luck and skills to control the bubble liquid concentration if DIY bubble liquid, 4) in some case, liquid contact may lead to equipment or device damage.

The best way is: use both methods for double confirm if allowed, since bubble is more visible.

User questions & answers

Question:	Would this work for a gas water heater
Answer:	Generally yes although you could attach it to a portable external battery for smartphone as the power input is 5 volt micro USB. Hope this answers your question.
Question:	What does it mean if it flashes blue & talks
Answer:	It depends on the ambient conditions but generally the limit for operation of a gas detector is around 4-5 years. Most gas detectors fail in 2-4 years due to the filament type sensor used. Consequently, regular testing of the device is essential to ensure operability.
Question:	i had to unplug this from the wall. I plugged it back in it turned blue then keeps saying something that I don't understand. can't find instructions
Answer:	Yes, the alarm will continue sounding until the concentration of combustible gas is less than 5% of the lower explosive limit.
Question:	About how long will this product last before it needs to be replaced? And how do you know when it needs to be replaced
Answer:	You could theoretically use the product with a battery and USB solar panel power supply but there is a limit if using with only a battery. For example, physical limit for 4000 mAh battery is 4000 mAh/110 mA = 36.4 hours assuming the FULL 4000 mAh is available for discharge which it is not usually as the 4000 mAh seen is rated by the battery manufacturer for charging of phones, not powering alarms. There is a natural drop of voltage as the battery discharges from ~5V to 3.6V. What can be done is get a battery with a larger capacity such as a 6600 mAh battery (or put multiple batteries in a parallel circuit if done safely).

FIND GAS LEAKS AT HOME:

Find the location of any natural gas, propane, LP or fuel leaks by running sensor probe along a gas pipe, fuel line, or fittings near any gas smells. Pinpoint fuel leaks from your lawnmower or car. Gas leak is found when alarm sounds and LEDs light up. Don't pay a technician's $100+ diagnostic fee when you can find a gas leak anytime with this propane & natural gas detector.



STEPS/TIPS ON USE: (see video at https://www.amazon.com/vdp/17873f5854174d4db2087794a60238be)

-To detect leaks while minimizing false alarms, turn the sensitivity dial upward toward (+) until the device begins to alarm away from any gas leak. Turn sensitivity dial downward (-) slightly until alarm stops and 1st LED just turns off. Now, any small increase of gas level (as from a leak!) will cause the alarm to sound.

-If alarm sounds prematurely, sensitivity needs to be decreased to prevent false alarms.

-Each leak varies in leak rate and background gas concentration, so adjust sensitivity level to find any leak.

-Allow device to warm up sensor for 10s until yellow “Warm Up” light turns off.

User questions & answers

Question:	is this detector constantly plugged in like smoke detector
Answer:	I suspect it can. If you have wind conditions of course that would affect how much gas the detector would pick up but if it was close enough to the source it should work
Question:	How often should a gas detector be replaced? Every 5 years
Answer:	No. LPG, natural gas, and town gas, according to the instructions.
Question:	Is the alarm constant until the situation is addressed
Answer:	I looked at the instruction manual and the box and it doesn't say anything about being UL listed. It is built in China but I don't know if that has anything to do with what is or isn't UL listed. Sorry I couldn't help more.
Question:	Can I use with a battery
Answer:	Hello, this product does not detect carbon monoxide, please pay attention when buying. Propane cannot be detected, but methane can be detected.

User questions & answers

Question:	Radon regulated states require that testing devices for real estate exchanges be approved by aarst or epa is this approved by either
Answer:	Hi there and thanks so much for your question! In order for a radon monitor to be approved by the AARST you need take a high amount of radon "counts" per hour within a specific time-frame usually (48-72 hours) which are done for real estate transactions. The Wave does not meet these requirements, it is designed for very accurate long-term measurements to give you a broader understanding of what your radon exposure is over the period time and not just a snapshot. However Airthings does have a monitor that does meet these requirements, our Corentium Pro. The Corentium Pro is fully AARST-NRPP certified and used and trusted by thousands of radon mitigators and house inspectors. If you have any other questions just reach out to us on the Airthings website and you chat with us directly! Again, thank you for your question! -Tom from Airthings Support
Question:	Is the hub required to connect with Alexa or other platforms
Answer:	You can use the Wave in 2 ways: 1. With Bluetooth: all that is required is to download the Airthings app (iOS or Android) and the app will obtain the measurement data using Bluetooth 2. With an Airthings Hub: the Hub is connected to a power source and Ethernet. It will automatically connect to your Wave using SmartLink and keep your data always up to date so you don't have to use Bluetooth. The Wave can connect to Amazon Alexa, with or without the use of an Airthings Hub - however, the experience is enhanced with use of an Airthings Hub as the measurement data is constantly up to date. Hope this helps!
Question:	What is the difference of gen 1 (which cost more) vs gen 2 which cost less? thanks steve
Answer:	The difference between the Wave 1st generation and Wave 2nd generation are that the Wave 1st generation provides measurements for radon, temperature, and humidity every hour. The Wave 1st generation is also not equipped with SmartLink which allows you to connected with the Airthings Hub to allow you to always be connected to your monitor. The Wave 2nd generation is much more similar to our Wave Plus under the hood with the firmware and is compatible with the Airthings Hub. The Wave 2nd generation provides a rolling 24 hour radon measurement every hour and the temperature and humidity are updated every 5 minutes. If you have any questions just reach out to our support team at [email protected] or chat with us on the Airthings website!
Question:	I have a mountain cabin and have no internet, by design! Will this thing work with my smartphone w/o being also connected to the internet
Answer:	Hi there - thanks for your question! This is the way it works: 1. you have to connect to the Wave via Bluetooth with a mobile phone or tablet. Bluetooth connections normally require you to be within approx. 30 ft of the device, and then you can view your up to date data in the app. 2. Once the data has been synced via Bluetooth and you have internet connection, the data will be further pushed to the cloud, enabling you to see your data on the online dashboard. So if you have your Wave in the cabin, you can sync via Bluetooth on your phone, and use your phone's internet connection to push to the cloud if you like! If your Wave is at your regular residence, and you want to continue monitoring while you are far away in your cabin, you should check out our new Airthings Hub, which enables your data to stay updated without the need for Bluetooth syncing :) If you have any further questions, feel free to reach out to us at [email protected], chat with us using the Chat function on our website https://www.airthings.com/en-us/, or read more about radon and our products in our Help Center https://help.airthings.com/en/. We'll be happy to help :) All the best from Lucy at Airthings Support

User questions & answers

Question:	Can it be used outdoors
Answer:	To be totally honest, I was very disappointed in this product. It did not work well for me with very coarse hair. I would have returned it but it was not worth the hassle for such a small price.
Question:	Does this specific unit detect radon
Answer:	I do not have the elite model but I believe it has a revolving head. I don't see a need for this feature as the lumina does a very efficient job of removing unwanted facial hair.
Question:	Is this alarm listed by Underwriter Laboratories
Answer:	YES SHOULD WORK ON SIDE BURNS
Question:	Does a carbon monoxide tester also detect propane
Answer:	My wife uses it on her entire face and chin whenever she has hairs that need to be trimmed. No stubbles seem to ever appear after use. So I would say it does an outstanding job. She is always pleased. Hope this helps you.
