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.

I mainly use this to detect electronic devices that don’t transit wireless signals. Works great in that aspect, as long as you zero it out before each use, in order to mitigate false positive readings.

Whether you’re using this to find high EMF in your home or chasing ghosts, this unit delivers. Easy to use and easy to read. It turns itself off after many minutes of use. It’s about the length of a hand and lightweight. We had fun going around the house seeing where we had high EMF. And if you are curious, yes, we even spoke to spirits and they “spoke” back!

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

The only reason I bought this E MF meter was to see how high the EMF level was on my earbuds and on my laptop when they're being used and when charging. I was pleasantly surprised to see that EMF level was pretty low on the earbuds and laptop. I use my Bluetooth earbuds a lot and was getting concerned that I might be damaging my noodle but probably not. The meter is easy to use once you understand how to use it. I asked GROK for specific instructions and It was much better than trying to decipher the instructions that came with it. Charging is easy and quick and it holds a charge for what seems like weeks especially if you don't use it very often. I'll be using it when I go ghost hunting so I'm looking forward to that!

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 detected o Units are in Volts per Meter o Unsafe level tends to be over 40 V/M - Meter's H-Field relates to the MAGNETIC FIELD detected o Units are in micro-Teslas or milli-Gauss o Unsafe level tends to be over 0.4 µT or 4 mG And 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'm concerned with all the 5G, fortunately I live rural. Smart TVS put out too much EMF, stay far away from tvs, even unplugged they put off dangerous levels 🥺🤨🤬

I was using this to check for energy, discharges or energy in areas. However I would’ve preferred an actual tri field meter this year. Doesn’t really give you what real tri meter does.
