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:	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
Answer:	no

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.

User questions & answers

Question:	Is there a way to turn off the alarm / sound
Answer:	yes, I think momentarily pressing the power button will do this (the alarm toggles on and off using the power button)
Question:	I stood on my deck and pointed the tester towards the power lines by my house. i did not get any readings emf showed 0. is this conclusive
Answer:	If the power lines are far enough away and not transmitting a high current load you shouldn't get a reading. The big huge transmission towers can show high levels of EMF. The lines to your home shouldn't show much. Old fluorescent lights and old CRT monitors can leak a lot of it.
Question:	can you test soil
Answer:	Hey, it seems that this tester looks like an instrument for testing soil. In fact, it is a household electromagnetic radiation detector. It is possible to measure soil temperature, but the data is not necessarily accurate.
Question:	Can this be used to measure emf for ghost hunting
Answer:	Yes it measures EMF and Temperature.
