I have heard that cellphones, computers, microwaves etc all give off these EMF signals. Can this detect small amounts like cellphones?

Yes. This meter is very sensitive. I will detect the signal from an individual cell phone or a nearby tower. It is particular useful when setting up wifi to make sure you are using the lowest power setting, and locate the wifi transmitter away from people.
1627606
That's what I got it for, and it is sensitive enough for that, but the one I got was either malfunctioning (according to manufacturer) or I couldn't figure out how to use it, despite the manual (which was confusing).
1627607
this is best for cell phone tower as i understand. this also works but you need another kind cheaper meter for emf you described. search online

Actually the amount of EMF in microwaves are not small, they are very high, over 200 micro gauss near the microwave front. This equipment can detect it, but the whole amount of EMF is not showed.
1627609
Yes, indeed. But you have to learn how to set the instrument, or calibrate it. the documentation won't help, although maybe their help line will help. I found an independant expert who was terrific. Google will help with finding these guys.

Yes it does but it is hard to figure out how to use it, call the helpline to set it up!

I recommend the Trifield 100XE EMF Meter for those sort of readings. It's cheaper, accurate, and easy to use. The extech is best if you want to measure radiation from cell towers etc.

This works on all radio frequency. When my cell phone is idle at home (using WiFi for APPs), there is no radiation. But when my cell phone is in a call (need to transmit), this detector went all the way up to the top red LED. It's a great tool to measure radiation quickly. It didn't give me fine reading as that hundreds dollar detector I used in NASA/JSC, but it close matches the reading to that expensive detector.

Yes, WiFi uses EMF to accomplish the wireless communication. While this device will not harm any equipment, it will eliminate the EMF used by the router, thereby disabling WiFi. If you have this device and your WiFi, cell phone, and radios are working, then it is not effective.

RF Radiation from cell phones -- yes if the unit is in close proximity (a few inches). It will detect the magnetic fields and electrical fields from a laptop (again in close proximity). Wireless mice and keyboards -- probably not. This unit shines at detecting magnetic fields and electrical fields. It also is handy for detecting leaks from a microwave oven.

As a point of scale, the EMF ratings for personal computers varies from 2mG to 20mG and for hair dryers from 10mG to 70mG. This information can be found in Consumer Reports.

New technology is coming out from some sets where they do not emmit all the time. Unfortunately I do not know what to look for. These units, in many cases put out more microwave RF than cellphones. I just read up on this today.

No. The meter is set for microwave-oven frequency over a certain range. I think it is too microwave oven-specific for accurate cell phone radiation readings.

no the meter only detects electro magnetic fluctuating fields. the human body produces .5 megahertz of natural emf this meter is very safe I recommend it highly

This is not actually possible. This unit is only a detector. It detects a small shift in a magnetic field. Your car is a big enough piece of metal to make a small shift in the magnetic field. This unit then sends a signal back to the receiver. However the signal is nothing near the same frequency or complexity of car security systems. I am sure something else "deprogrammed" your cars security

Hello, Brent V. With cellphones or wifi the potentially harmful radiation is radiofrequency (mostly in the vicinity of "microwave oven" radiation, around 2.4 Ghz) because these frequencies are particularly prone to do eventual damage to us. If I correctly recall, there are devices for measuring "rogue microwaves" but they are mostly to detect badly sealed microwave ovens.
889885
Yes, these devices measure the electromagnetic radiation from cell phones, cell towers, and depending on the range of the device, power line radiation. However, the inexpensive models are not very accurate. If you are experiencing EMF sensitivities, then you should search for a more professional meter.

In my opinion, the most important thing to keep in mind with this device is "phase". It "detects" better at specific angles to the EM source. So, just proximity to an energy source will not always create a reading because of the phase +/- of the source. Don't use sudden movements but rather steady, deliberate ones. Be aware of your temperature changes when the EMF reading changes, i.e. greater than 1-degree temperature changes. Don't miss your EVP opportunities when either reading changes! - Joe from O.R.C.S.

No, It only used to measure electro magnetic radiation in radio frequency range such as radiation from microwave tower, Wi-Fi, Microwave oven, wireless communication etc.If you want to measure EMF for AC unit motors & other home motors, you need a meter which can measure EMF in power frequency such as Trifield 100XE meter. Thanks

I do know it measures the EMF radiation from Wi-Fi. I do not know the technical specs, however when I tested it in my living room (which faces the neighbor's smart meter) - the beeping on my Cell Sensor EMF Detection Meter just went to the highest danger level. Hope this helps.

Everything is emp proof if it is in a faraday cage. Otherwise any electronic will be destroyed. (Including this)

I believe that this device works well for EMF; but, I need a debice that is inexpensive to measure ion levels in my home environment
