Features
- True EMF protection starts with detection. Our emf meter helps you: 1) Find dangerous radiation hotspots in your home/office, 2) Scientifically verify if EMF shielding products actually work by comparing before/after readings, and 3) Continuously monitor protected areas to ensure they stay below the 0.4T safety standard. The smart way to shield - test first with our professional-grade detector for guaranteed results.
- PRECISE MEASUREMENT: ERICKHILL emf reader built-in electromagnetic radiation sensor displays the radiation value on the clear LCD digital display after processing by a control microchip. It can test magnetic field radiation with optional units mG/T and the electric field with unit V/m. Electric field Range: 1V/m-1999V/m,Alarm threshold: >40V/m.Magnetic field Range:0.01T-99.99T / 0.1 mG - 999.99 mG,Alarm threshold: >0.4T / 4mG.
- Sound and Light Alarm for High EMF Levels: When the electric field exceeds 40V/m or the magnetic field surpasses 0.4T (4mG), the screen turns red, the indicator light flashes, and the buzzer sounds an alarm to notify you. A mute mode is available for quiet environments.
- Versatile Applications for Home and Office:Suitable for detecting low-frequency EMF radiation from household appliances, including TVs, computers, microwave ovens, induction cookers, refrigerators, and power lines. It helps identify EMF sources and optimize your environment. This EMF detector is useful for home inspections, workplace safety, and even paranormal investigations.
- Easy-to-Read LCD with Data Hold. The data hold function allows you to freeze readings for easy recording. The LCD screen ensures clear visibility, even in dark environments. The device automatically powers off after 5 minutes of inactivity to help conserve battery life.
- Important Measurement Note:Magnetic field (MF) readings may show 0 if the tested device is not powered on or if the radiation level is below the meters detection range (0.1mG999.99mG). For accurate results, ensure the appliance is switched ON and operating, and position the top sensor of the meter close to the source.

Works perfectly! Great for the price. It detects very easily and quick. Doesn’t weight much.

The media could not be loaded. First off, It was delivered so quickly literally in a cpl hours. It came fully charged and well packaged in a attractive box. It came with an instruction manual and a USB cord for charging. I have no other testers to compare the readings to. However, places and things we knew to be hot spots like the router etc. This thing did great at detecting . Oddly enough items I thought would be relatively low turned out to be very high. Originally our concern was the smart meter on the wall outside our small bedroom. And yes its reading higher than we would like. It is very easy to use and it will store data. It has a light and sound alarm. You can turn that off if you like. The instruction booklet describes how to do v To do that under operation instruction pages 4- 5, item #5 Buzzer switch. If the accuracy is on point and I have no reason to believe it isn't. Its a nice tool. It seems really is wise to own one. You probably have a smoke detector, burgler Alarm, Co2 alarm and many others. The emf readings in my house really woke me up to the hazards silently destroying my cells ability to divide amongst many other things. This seems pretty decent. Go fot it!

Bought to see why people in my house weren't sleeping good. Overally indoors it measures plenty of electrical when you get close to things, some magnetic (significantly less though) and pretty much nothing on the radio mode. It's really lightweight, I thought it would have been heavier, sure looks that way. I don't know where you could measure radio waves with this thing, maybe if I turn on the radio. I thought we were surrounded by radio waves everywhere. We know we're surrounded by emf if we're in the same room as a wireless router, but you have to get close to the router for the numbers to actually go up. There's two kinds of waves in emf, and this one only measures one kind. You can get wifi signal on your phone in another room from your router but this thing won't pick up on it, even if you're a few feet from your phone. If you say hey Siri and you're only on wifi this thing should go off, but it doesn't. If you really want a better one spend $250-300

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.

This was one of the top ones recommended on several review sites. I did not understand what it meant when it said it did not detect a certain type of radiation, but I realize now that it meant it does not register Wi-Fi or cell phone emissions. That being said, it can certainly detect all the EMFs from your outlets, light switches, televisions, computer screens etc. I can use it to follow the wiring in the wall. It's almost freaky and scary. The red alarm goes off if I'm within a couple feet of the wall so it's hard to find a place to put your bed if there are outlets and light switches around you. The EMFs increased dramatically if the outlet is being used or the light switch is turned on. And my entire recliner is in the red zone because it is a powered chair with an electric control to raise and lower the feet. And I also know just how far to stand back from the microwave. You have to spend twice as much $ to get one that checks your cell phone and Wi-Fi radiation, but after I discovered all the EMFs in the house, including what's coming through the walls from the wiring, I think I'd rather not know lol.
