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

Question:	What is the frequency range of this device
Answer:	Hello Rafael, Thanks for reaching out to us! Frequency range is 50hz to 3000Mhz. Please let us know if there's any other way we can help. Kind regards, Sherrylyn Customer Service, American Lifetime
Question:	how many does this come with
Answer:	One, and its very entry level. I would recommend a trifield meter or something more advanced instead.
Question:	Hello, is it work for detecting smart meter radiation level
Answer:	Yes, it should detect a magnetic field similar to WiFi. It will only detect the smart meters electrical field when close by. Word of advice, if you buy this meter do not power on the unit close by what may be putting off these fields. Instead, power on the detector further from any other signals then walk towards what you want to measure.
Question:	Is this also an rf device or strictly an emf device? my understanding is emf is electrical and rf is radio frequency like wireless
Answer:	While this is a great way to count the emf power. Some of who are interested in radio have been using an alternate solution for the last 60 years. Simply tune a portable AM radio to an unused. quiet spot on the dial. Turn the volume up, then walk around your home or plant and "listen" to the EMF. Use the radio like a Geiger counter to point toward the offenders. You can actually hear the differences, and rate intensity by the loudness of the sound. Interestingly, some will have a buzz, some while whine, some will pulse, some will gurgle. Some will radiate a foot or less, some will radiate 6 feet or more. Interesting to listen to the difference between a wireless phone charging pad when the phone is on and then off the pad. The same can be done in your car, with the radio tuned to a quiet "AM" spot as you drive past power transformers, overhead high tension power lines and etc. During electrical storms, you can pick up lightning from more than 100 miles away as a sharp "crackle". If lighting is closer, count the seconds from the "crackle" until you hear the boom to calculate the distance in miles. Still a device like the Cambridge Labs EMF meter are very useful, but there are interesting ways to compliment it or even without it by using portable AM radios. Some of us have been using this AM system for many years to route out interference to our shortwave radios and etc since the late 1950's!

User questions & answers

Question:	What are the safe levels, and what are the unsafe levels to be around
Answer:	stay away from your microwave when its on. Thats the only thing that made the meter go off that it was not touching. Even the electric box was safer a couple feet away. I wouldn't sleep on the other side of a wall from one or over a power line. 10 feet away from microwave the meter was going off when it was on. Computer, tv , phone charger and stereo you had to almost touch to register.
Question:	Is this device adequate to test levels of radiation due to high voltage power lines
Answer:	Yes, it can be used to test levels of radiation due to high voltage power lines.The closer the distance is, the greater the radiation intensity is.
Question:	What is mg/ut, and when one should make a switch from one to another
Answer:	In the International System of Units, the unit of magnetic field strength is N·S/C·M, called Tesla, abbreviated as T, which is represented by T. Another unit system is often used in magnetism - Gaussian. In Gaussian, the unit of magnetic field strength is Gauss, expressed in G. The conversion relationship between Tesla and Gaussian is 1 mG=0.1μT
Question:	Can this measure radiation or mMV waves from a 5G tower in my front yard
Answer:	NO ! the radiation frequency of 5G tower is more than 2600MHz,The EMF meter can only test the range between 30-300hz. The EMF Meter be used to test the radiation of Home Appliances: TV, AC, Induction cooker, rice cooker, computer, electrical wires, etc. But it can not be used to detect mMV waves from a 5G tower, we Suggest you choose a RF meter to detect it.
