ERICKHILLEMF Meter, Detects Electric and Magnetic Fields, Handheld Digital EMF Detector with LCD Display, Sound-Light Alarm, Rechargeable Battery for Home, Office, and Appliances (Blue)

Works as expected. I use it mostly for lower frequency EM detection from power lines or power equipment. An an electrical engineer I don’t see any problems with it. People need to realize its upper frequency limit is 3.5Ghz so it will not detect cellular signals or wifi.

I use this to measure the EMF emission from Starlink when in use. This let me know how far I need to stay away from it.

Doesn't stay on for long and can't set the threshold for the alarms so it's flashing red if you're around rf or magnetic fields. Does appear to work when driving under transmission lines.

i am usually pretty stingy about my reviews but i give this a 5 star because it saved my life. i was using it outside my house and got hit with a severe emf spike and had to seek cover indoors. this also correlates with the exact area where previously i had a serious car accident related to an overheat condition and a broken hood latch. this lead to a line of medical inquiry and tests where I realize i have a severe EMF sensitivity. Also, the level of intensity of these EMF spikes in this area actually have potentially caused the various and frequent electrical issues in my car. From the data gleamed from this device I have began designing better electrical failsafes for my motor vehicle.i dont know how accurate it is. for 80 dollars, it fits what i need perfectly. just a great residential meter for normal people that is straightforward and easy to understand.I have several times forgot to turn my RF off on either my cell phone, or router. This device will pick it up so i can remember to turn them off before going to sleep. Also, I learned how dangerous microwaves can be, and now generally just stay 6 or so feet out of the field strength changes when they are on.Thank you to the engineers who designed this, the company and manufacturers.Very happy customer.

Great tool works good

Idk..this one was not my favorite. Or maybe the other one I had was not my favorite? My other emf reader would pick up cell tower waves, this one barely registers them so now idk what to believe.. im returning with hopes of finding one we like

The media could not be loaded. Certainly one gleans some very interesting information from this meter... but it could be almost terrifying out of context.One of the things I would point out that this product could improve is the DOCUMENTATION. The manual with the product isn't very thorough. (And yes, rare for me: this time I actually DID read the manual provided before proceeding because I didn't know at all how to use it.)But even after reading the manual, all I learned were the parts of the meter and screen items... very little about HOW TO USE or how to APPLY what I learn from using the meter.So, in that gap, I will offer a few basic pointers:- Meter's E-Field relates to the ELECTRIC FIELD detectedo Units are in Volts per Metero Unsafe level tends to be over 40 V/M- Meter's H-Field relates to the MAGNETIC FIELD detectedo Units are in micro-Teslas or milli-Gausso Unsafe level tends to be over 0.4 µT or 4 mGAnd it must be noted that testing immediately near any radiation/magnetic source like a router, microwave oven, TV, charger, etc isn't the same as testing a "reasonable distance" from these.Danger comes in where the ambient or background levels of EF or MF exceeds these "relatively safe" levels, not where sitting right on top of something.So when you're testing, walk around a bit. Try to put the meter down or prop it up, or place it on a tripod or something (so your body's own ability to conduct interference isn't in the test loop).This little meter is quite good at testing and detecting radiation.The more you KNOW, the more you can PROTECT yourself against risks.One of the BIGGEST OFFENDERS, I learned, was a SUPERSONIC BUG ZAPPER and CO2 sensor thing we have plugged in. It really went off the charts in both Elec and Magnetic Radiation overages!!!

I used this on my cellphone, tablet and Kindle, and they showed no radiation in the 'warning' range. However, out walls and electrical outlets show high warnings. I found that my reading chair and computer were already outside of the warning range (for instance, a charging cellphone is in warning range - just move it a foot or more away from you).Bose wi-fi radios show warning ranges even when not on - just sit out of range.I have also since unplugged a power strip under the bed, and am unplugging an extension cord at night that showed warning ranges where my head is on the pillow at night.Very informative for reducing EMF exposure.
