User questions & answers

Question:	Will this work in India/ Europe
Answer:	Yes, this meter will work anywhere in the world. This one version will measure both 50 and 60Hz power regions.
Question:	Will this pick up UHF and microwave
Answer:	Thank you for your question. This meter will detect all three types of electromagnetic pollution.; AC magnetic, AC Electric and RF/Microwave.
Question:	Does this pick up emf/rf at a distance, or do you have to hold it right next to the source
Answer:	This meter will pick up EMF/RF at any distance, as long as the field is strong enough.
Question:	Does this read digital RF from cellphone towers, wifi, wireless LAN, etc
Answer:	The TF2 RF section is great for measuring the EMF emissions of cellphone towers, Wi-Fi and mobile phones. When reading RF emitted by digital devices, such as mobile phones, Wi-Fi routers and smart meters, the Peak Measurement (small numerals in the upper-left of the display) is of more interest than the Field Measurement (large numerals at the bottom). The information from digital RF devices is transmitted in brief packets that occur irregularly (perhaps once per minute with smart meters and several times per second with Wi-Fi transmitters or mobile phones that are in use). The Peak Measurement detects these packets and displays the strongest packet for several seconds before resetting itself.

User questions & answers

Question:	What's the difference between this and $300+ rf meters? my 13yo son is doing a science fair project on cell phone radiation. thanks
Answer:	This EMF meter measures 60 Hz (up to 300 Hz) frequencies. That's basically power line type electro-MAGNETIC radiation. The cell phone radiation is RADIO frequency radiation in the Mega or Giga-Hz range. So, this meter will not work for his project.
Question:	Can this be used to detect electrical radiation from electrical boxes on the side of the apartment building where we are living? we are concerned that there might be a lot of electrical toxicity coming from that into our unit
Answer:	Yes, but it only detects EMFs. There is no such thing as electrical toxicity, but there is ionizing radiation, from high voltage electrical fields, or high strength magnetic fields, hence electromagnetic field. Just look up the current data for recommended levels of exposure, then set the meter for that level. Then examine the areas you occupy for the length of time required for exposure limits. If you exceed the limits, replaced the device causing the problem, or relocate the occupied area for less total time. Another comment talks of all the different devices. I can tell you right now, every single AC device produces EMF. All of them. It's not about whether you are exposed, it about how much, and for how long. The alarm clock thing has been known for over 40 years. Just like CFLs if used within less than 15in is cancerous.
Question:	Can it be used to detect ghosts
Answer:	This will not detect ghosts, even if you believe it will. This detects electro magnetic fields. So unless you believe ghosts are produced every second by electricity, the Earth is surrounded by a ghost, and everyone's phone houses ghosts, this will not help you.
Question:	Has anyone had a professional come and collaborate your reading from this meter
Answer:	Yes. I tested it with calibrated equipment. It reads 0.0 milligauss up to 1.6 milligauss of ambient magnetic field. In other words, you might think there's no field when the meter reads zero, even though there could be as much as 1.6 mG present. At higher fields, it actually reads 2.5x too HIGH (reads 250 in a 100 mG field for example)). WAY inaccurate. Also the confused "English" manual claims it also reads "electric" field. It doesn't. And it doesn't read RF, microwaves, cell towers, etc. either. However, the meter is poorly shielded, so when placed near a leaky microwave oven, the meter circuit is interfered with, and it sometimes reads something, although the number is meaningless.

User questions & answers

Question:	All i want to know if this detector gq emp-390 will detect 5ghz wifi signal and 5g cell phone
Answer:	Yes it will detect 5GHz signal but not in all modes of operation. If it is the predominant source then the general Radio Frequency RF mode reading will reflect it. If it is a source mixed with others than all sources will be reported together as one value (sum/average over time...unknown. most likely average). It will not detect it in spectrum analyzer, by frequency, and show it's individual power level. Spectrum analyzer will detect 2.4GHz wifi. 5GHz is out of range of spectrum analyzer as is everything greater than 2.5GHz. It might detect presence of 5GHz data packet bytes in digital mode but I don't know for sure, have not tested this.
Question:	Can it tell you how much emf your cell phone emits
Answer:	yes it does, in 3 scales. some readings read a voltage per meter and another is electro-magnetic reading, I searched through alot and after receiving this I found it to be the best affordable technology in its class, and it even automatically identifies the difference between cell phone and power line EMF in digital readable format.
Question:	Will this device analyze a 5 gig wifi signal like it does a 2.4 or
Answer:	Yes, it does analyze 5 Ghz frequencies. If you are asking whether it will analyze 5G as in 5th generation Millimeter Waves, the answer is NO.. 5th Generation 5G will use frequencies between 30Ghz and 300Ghz... You can get one that costs about $40,000... As in, they are not available to the public .
Question:	Is the 5g wifi signal the same as the new 5g cell phone signal? will it measure the new 5g phones? it is confusing: it says: "rf up to 10 ghz
Answer:	The 5G wifi is referring to 5Ghz Wifi, and it is covered by this meter RF band. The 5G cell phone network is referring to 5th Generation cell phone network, it is nothing to do with 5GHz, basically its base band is much higher than 5Ghz

User questions & answers

Question:	Can it be plugged in to external power
Answer:	No, this EFM Meter can not be plugged into an outer power source.
Question:	I'm a person with ehs, i want to know if this meter might be good to read the radiation from cellphones, high tension lines, cell phone towers, 5g? ty
Answer:	Honestly, you probably could read the output of them in Milligauss or Microtesla but you would have to get pretty uncomfortably close. For reading radiation of those things and not endangering yourself I imagine you would need a pretty powerful EMF Meter. After doing some quick research on this, you would need something along the lines EMF Detector with the detectable range of something like 10 Hz to 10-12 GHz. For radiation coming from Cell towers you will be in the 50-10,000 MHz Radiation from high tension lines you will be looking at under 5 MHz by a great deal
Question:	Can it detect the variables in earth's magnetic field
Answer:	Thinking logically about it you would think yes because weather it be earth's magnetic field or a magnetic field from say inside your house from an appliance they would both be detected. But that is just my thoughts about it so you would need an answer really from the manufacturer.
Question:	Can this device detect radiation from nuclear fallout

User questions & answers

Question:	How do I measure radio frequency in hertz or convert V/m to hertz
Answer:	Greetings: Unless I am not "firing on all cylinders," V/m is Volts per (sq.) meter; this is a measure of electrical potential or intensity. The "Hertz" is a measure of cycles per second of an alternating voltage or current. These are two different types of measure, and there is no "conversion" of one to the other. - Paul B. Searles, Retired Master Chief Electronics Tech, US Coast Guard -

User questions & answers

Question:	Why are reading alot higher when held in my hand versus setting on table (ball not touching anything)? also why read higher on Y axis
Answer:	Hello, The reason for higher reading might be that your body serves as an antenna or a reflector of the signal back to the meter. Please ensure that your cell phone turned off when you do the measurements.
Question:	Will this meter measure the frequency from a high voltage power line running in front of our land? Need to know how far to build for it to be safe
Answer:	Hello, The HF-B3G won't measure low frequency EMF. In order to do so we recommend you using the MG-300 or the MG-2000T. https://www.amazon.com/dp/B01CGVBP5O https://www.amazon.com/dp/B01HQBRZ9O
Question:	Does this emit any kind of rf itself? i am highly sensitive to wi-fi radiation. it effects my heart condition. so can't have anything that emits it
Answer:	Hello,The RF Meter is only measure the RF signals. It does not emits RF.
Question:	What kind of battery does this use? Is it internal and rechargeable or do you place the batteries inside and if so, what size / type battery? Thanks
Answer:	I am sorry for the delay in my answer. This device uses regular 9v battery (comes with it). You can use any rechargeable 9v battery. But, before you buy this device, I need to let you know that I find it to be no so accurate. The numbers keep jumping up and down, in high values, making the device useless. It has a way to lock on the max value, but does not show the real time number. I am going to send the supplier an email asking them if this is expected. I used to have an analog one, and it showed some small/ minute variation in readings, but still manageable. I bought this digital device, because I thought I can get a better, accurate reading. This might be more detail than expected, but hope it is useful.

User questions & answers

Question:	Is it provided with a calibration certificate
Answer:	The ultrasonic waves will clean and remove any debris from dentures but if dentures are stained a cleaner would be needed.
Question:	At what range will this device detect an RF source
Answer:	It is a fine tuned vibration. I see some water motion but it is very lite. My dentures come out clean and white. I always add whitener and disinfectant to the water.
Question:	Will this detect the new 5G cell phones and transmitters
Answer:	I use mine for jewelry and airbrushes. Sorry, no experience with dentures. I use distilled water with a drop of Dawn dish soap (to break the surface tension) for the jewelry and same for the airbrushes except I add some Simple Green. I usually dump the solution after each use since it is a small amount. The unit is high quality and has a 5-minute run time which is usually enough to get everything clean.
Question:	Does your device come with the datalog, in which you can export the data and generate the graphics in a specific software? And on the device screen ca
Answer:	Yes, it works well for removable dental applicances. The unit costs more than other appliances advertised for that purpose but appears to be made better and can be used for a variety of applications besides dental.

Product description

Cell towers | Smart meters | WiFi signal strength meter | Microwave ovens | Power lines | Transformers | Home appliances | Outlet Boxes | Paranormal.Note :1. To measure RF from the router, the operation mode of the meter needs to be in RF mode. We can achieve it by pressing the mode button. 2. The LCD back light can be turned on/off manually by pushing the 2nd button to get into the Hold mode first then toggle the 1st button to cycle through the sound-on/light-off, sound-on/ light-on, sound-off/light-off, and sound-off/light-on setup, then push the 2nd button to get out of the Hold mode. The LCD back light consumes a lot of battery current when it is on, therefore the default is auto back light off after 10 seconds to save the battery power.
