User questions & answers

Question:	Can i reset the comfort range? 79 degrees f is much too high to be comfortable imo
Answer:	Actually the temp does have a bearing on the comfort indicator as amorina states. It will need to be a minimum of 20 degrees and between 50 and 70% humidity to indicate as comfortable. I agree with you that this is a little high and perhaps 18 would be ok. Other sources state that 40% humidity is ideal so who knows!I think just go with what feels right. In answer to your question though unfortunately the comfort range can not be reset or altered.
Question:	is this made in usa
Answer:	In China. I bought 3 of them, but don't find them useful. The setting for humid, dry, comfort is inaccurate for a relativity level reading in a home environment. At least in the Midwest region. They say 49% is dry when in fact it's too much for a home to carry, at least in the winter colder temps.
Question:	Has anyone had this long enough to know if the battery will last at least one year
Answer:	This is probably too late to be of use to the original poster, but maybe it will help someone. I purchased mine in March of '17 and the unit just died on me this past weekend, I was still using the original battery. I changed the battery and the thermometer was still dead, but that's less than $10 for nearly 2 years of service on a single battery.
Question:	Any way to calibrate temperature
Answer:	Calibrate means that you adjust your measuring tool (e.g. thermometer, hygrometer, speedometer, etc.) to give a known value when it's measuring (detecting) that value; you usually do this by adjusting a screw or other mechanism that results in the unit showing a 'reading', or measurement, of that known value on its display or output. This unit does NOT have any calibration adjustment.

User questions & answers

Question:	Does this device record the temperature changes throughout the day 2 days or 3 days that you can review later
Answer:	The first part of your question is yes, it records the current temperature. The answer to the second part is no, it only gives the current temperature of the location it is placed; i.e., bedroom, den, bathroom, outside etc. It also gives the humidity.
Question:	Could this be used in an egg incubator to give a more accurate reading than the built in thermometer-hydrometer
Answer:	This little device is very accurate we use it in our bath rooms because we are trying to get humidity down so we can install our flooring
Question:	Does this hygrometer need calibration? It is reading 15 degrees low
Answer:	Just got mine and the humidity reads 7-10% low. I did the salt water calibration test twice and it never got over 65%. The hygrometer is useless.
Question:	Does this have a calibration feature? I want to be able to periodically recalibrate
Answer:	No, it does not. I find it to be quite accurate, though! I would imagine that you could just remove the battery and re-insert it to recalibrate. But manually, no calibration feature. I have baseboard heat with no thermostat so this really helps me know room temperature and humidity. Good product!

User questions & answers

Question:	Does is come pre calibrated
Answer:	I spent about 5 seconds actually reading the description which states it is pre-calibrated. Probably took you 100 times longer than that typing your question that had the answer right there. On top of that, you should always calibrate any hygrometer you buy your self. I bought two of these and one of them was off by 2% and the other was off 3%. Since I took the time to calibrate it instead of trusting the "pre-calibration", I have 100% accurate hygrometers.
Question:	For those using this hygrometer for string instruments - any using it to measure the humidity for a small studio (10x
Answer:	Certainly. Remember that things like the sun, or other heat sources may affect the reading. I'd keep your instruments and this hygrometer out of direct sun.
Question:	oasis offers a 5 year warranty for their hygrometer...do you
Answer:	It's $20 dude, are you really worried about a warranty?
Question:	Can this be used as indoor humidity monitor? Will it be accurate
Answer:	Yes. Although its for cigar humidors it will work for measuring indoor humidity. They are very accurate and can be calibrated with a Boveda 75% calibration kit or the salt test. To do salt test simply put table salt in something like a bottle cap and moisten the salt with a little water. It should not puddle just be moist like you were making a paste. The place that along with the hygrometer in a ziploc bag and wait 24 hours. It should read 75% RH. If not then simply depress the set button until it goes into calibration mode then enter the offset by depressing the min/max button until your desired offset is displayed then press set again. Example if its reading 74% you would want +1%.

Product description

Know your environment

An all-in-one digital thermometer and humidity gauge, the AcuRite 00613 Indoor Humidity Monitor gives you a full picture of your indoor world. With an easy-to-read, at-a-glance display, you may access both humidity monitoring and accurate temperature as the need arises.



Features:

• Indoor hygrometer (%RH)

• Indoor thermometer (degrees Fahrenheit and Celsius)

• Humidity Level Icon indicates high, low or ideal indoor conditions

• Daily high and low temperature and humidity records

• Flat stand, clip, and magnet options (for mounting on a tabletop, vertical surface, or metal element such as a refrigerator)



Why an indoor air monitor?

Using a temperature monitor and humidity meter will allow you to ensure proper indoor humidity. This can yield important skin, allergen, and other health benefits:

• Too much humidity can encourage the growth of mold, bacteria, viruses, fungi, mites and other asthma-inducing agents

• Overly dry air can lead to nose irritation, skin irritation, breathing difficulty, and damaging static electricity

• Correct humidity can encourage plant growth, and assists with the comfort and health of pets



This humidistat will help you improve your home environment through the power of knowing. When you need accurate, think AcuRite.

• Indoor relative humidity
• Indoor temperature, including daily high and low information
• Simple easy-to-read display
• Clip and magnet mountable
• American Based Company in Lake Geneva, WI, USA

User questions & answers

Question:	Does the HIGH/LOW reset automatically? I need one that doesn't reset until I reset it
Answer:	It uses three 12 hour time blocks (36 total hours) per the 7/19/16 response and automatically resets. This screws up being able to determine the 24 hour hi-lo I was used to with another model. I much prefer the one that auto resets every 24 hours from battery insertion. On the latter, by inserting the batteries at midnight, a daily hi-lo was always available. With the 36 hour look-back this daily Hi-Lo feature is totally useless IMO.
Question:	does the unit have a backlight? Thanks
Answer:	ASSUMING THEY HAS BACK LIGHT -I BOUGHT 3, A FLASHLIGHT IN A NECESSITY AT NIGHT, AND THEY MAKE CUTE PAPER WEIGHTS!!!!!
Question:	I'd like to know if it also makes the measurement in degree celsius
Answer:	No it doesn't :( celsius x 9/5 + 32
Question:	accuracy
Answer:	You might want to check out my review of this product (written 11/17/15). I bought 3 of these, compared them to each other for accuracy in temp and humidity and gave detailed results. Overall summary is, 2 of the units were pretty good with both humidity & temp accuracy (most likely acceptable for most people's use), the 3rd monitor was not. It's a crap shoot as far as getting one that's in the satisfactory range of accuracy for both readings, I think.

User questions & answers

Question:	Does it need aa or aaa battery
Answer:	Yes, it use 2 AAA batteries.
Question:	How accurate is this unit
Answer:	Very accurate same sensor used in Davis VP2 Pro stations. Temperature +/- (.36F) full scale, +/- (2%) humidity. Most SHT31's won't hit 100% humidity but neither will $800 Vaisala and why the NWS ASOS stations jumps to 100% when sensor reaches 98%.
Question:	Temperature is only in Fahrenheit unit or the unit can be changed to Celsius
Answer:	Both Fahrenheit and Celsius. This pro device responds faster to surrounding humidity level compared to the regular device and more accurate.
Question:	Can it be calibrated
Answer:	Not only can it be calibrated, it should be calibrated. Google the "salt test" for Hygromters. The salt test provides a reliable and reproducible 75% relative humidity to test the accuracy of your hygrometer. Mine was 14% off, but spot on after calibration with the salt test.

Product features

User questions & answers

Question:	Does this have the attached magnet
Answer:	No, it's made to snap into a panel cutout. Also, I don't know really how much I'd rely on the numbers. I use it to gauge the temp in my office and mostly I compare the differences form day to day as opposed to knowing exactly what the temp is.
Question:	How do you change temp from C to F
Answer:	The sensor is already showing F° and as far as i see there are no buttons to change it
Question:	My hygrometer was already turned on when I unpacked it and it stopped work after 2 days. Would anyone know if I can fix this issue
Answer:	I don't think they're able to be turned off, mine also came turned on but works fine. I'd say return it, says it has free returns
Question:	Are you able to change the calibration on these
Answer:	I just looked and can't see any. This is a cheap unit. I don't think you can ask much of it.
Question:	C and F ???? or only F
Answer:	Only F. No C.
Question:	The top picture shows temperature only. The others show both humidity and temperature. Is there a switch between these displays
Answer:	I bought these and love them for monitoring humidity in my woodworking shop. The large (main) display is the humidity and the temperature is displayed (small digits) in the upper right-hand corner. There is no switch to switch humidity and temp to what the main (large digits) display is though. Hope this answers your question.
Question:	Are there batteries included
Answer:	Yes
Question:	Are these for wall mount? If so, probe seems to get inside the wall. What would be a typciall installation
Answer:	This is designed to be inserted into an opening (cut into anything) and sealed so that the internal conditions can be read from the outside, such as with a cloning propagation chamber.

User questions & answers

Question:	When does it display “wet okay dry” on the screen
Answer:	Well, I know I've seen "dry" when it's reading under 47%. As for "wet", I can't say at what point it triggered. Only that a steamy bathroom after a shower got the "wet" environment alert at well over 70%.
Question:	What are the measurements of the hygrometer in inches
Answer:	The display shows the temperature and humidity level in the area you have the hygrometer. There are no inches displayed, you may be reading the size of the hygrometer.
Question:	Is this waterproof
Answer:	no it clearly states it is NOT in the item description, Im guessing the seller prob updated since you asked so not sure why they didnt also answer your question
Question:	How do you calibrate the humidity
Answer:	It should come calibrated. Do you mean how to calibrate what values it says are dry, comfortable, or wet? I'm not sure you can do that.
