Product Description
Electromagnetic field meter (EMF meter) can test electric field radiation and magnetic fieid. Time, distance, and shielding actions minimize your exposure to radiation in much the same way as they would to protect you against overexposure to the sun.
Clear LCD Screen Display
When the EMF detector reading more than 40V/m or 0.4μT, it will be warning and the screen turns red, the indicator light will flash and the buzzer will alarm.
EMF Detector will automatically shut down after 5 minutes without operation.
How to turn the sound on and off
After startup, long press “AVG/VPP” button to turn sound alarm on or off. If buzzer is turned on, volume icon will be displayed on screen, the alarm will sound.
Note: Doesn’t measure RF (radio frequency).

This little device let me see in how much emf was around my bed and other critical place on the house. I also now does not carry my iphone on me. I put it on my backpack instead. Very reasonably priced and super useful.

Works great, now I’m more paranoid than ever! LolMy walls are giving off over 230 v/m , kinda strange.2 feet away it’s still giving off 40 V/m. ????

I really like the rechargeable element of this emf detector to not have to mess with so many batteries. It’s visually easy to read with a nice red flashing when readings get too high.Two things that would make this perfect: 1) If you could set the upper limits before it alarms as the settings seem a bit too low and 2) when you set the base settings (example: F/C for temps), it clears them when you power down. Not an impediment, just an inconvenience.

Like the reader’s navigation. Was really surprised of how MUCH exposure I had to EMF items! Great product. ????

I know that I cannot expect precision readings from such an inexpensive meter as this, but all I wanted was the ability to make some comparisons—qualitative rather than quantitative—and this meter seems to do the job quite well. (I say “seems” because I haven’t compared it to an expensive meter, which would cost more than $200.) This meter is very user-friendly, and the instructions included are complete and easy to understand. I was immediately “up” and testing throughout my home, with some very instructive findings: Not surprisingly, the most alarming finding concerned the electrical smart meter. And the TV was a hot spot even when it was turned off. And of course the mobile phone.That’s good enough for a positive review, but what really won my heart is the high quality of customer service. I wrote them to ask a couple questions about what seemed to me anomalous readings (but ended up being perfectly reasonable). I didn’t really expect a response, but a rep quickly responded and, in answering my questions, took the time to teach me a bit about electrical fields and certain electrical devices (including mobile phones). Not only that, but when I didn’t reply to her within a day, she wrote again to make sure I had received her previous email!I happened to mention that sometimes the meter “sticks” on a certain reading, and I have to turn off the device, then turn it on again to get it working properly. I said it’s not a big deal—and it wasn’t—but she expressed how keen they are to have happy customers, so she sent me another meter—without me even asking for that. (The new meter hasn’t been sticking.) And it was all done with genuine friendliness! Truly, I’ve never seen customer service like this.Would I buy from these people again? Absolutely! I wonder what else they sell …

I knew going in that this wasn’t gonna be anything like a trifield scanner. I had various parts of my house tested in the past so I knew what areas were higher than others. And this confirmed that but helped me identify a couple new areas. But I have tested with accuracy in the past with faraday cages to lower the signals of a WiFi router and other devices and this thing didn’t read lower. It stayed consistently high, Higher than when I had it tested years ago.So I’m not sure why it doesn’t detect lower signals and frequency when they are covered. Some people have said these under report. I have seen these over report as well.But if you want a “general” idea about EMF frequencies in your house and your someone who like me is sensitive to stuff like that this is good for getting a general idea.For example in one bedroom in a 3x6ft section the signal shot up to 1/3-1/2 as high as a microwave. I was very surprised by that. Then I remembered that an electrical panel box was directly below the wall in this part of the house. Weirdly we have another panel box in the garage and it hardly gives off any EMF unless you’re right up on it. But this was really consistent in a 3x6ft section. And have made some adjustments to that part of the room that it’s not a place I would spend a lot of time there. No bed or chairs will be in that section. I’m not worried about standing there for a minute but I wouldn’t sleep over night with signals that high.And the microwave was very strong at 15-20ft away 360 degrees around the house. Making me reconsider using that very much.Anyways if you’re looking for exact specific numbers this is not the device for you. But if you want a general idea, this is fine.

I got this EMF detector for a paranormal investigation and I’m so glad I did! It is very sensitive and actually works! I tested it at home first (which I know is not haunted) and the only spikes were next to outlets and stuff connected to power. Unless I got a message or something, it does not detect anything next to my watch or phone.I was pleasantly surprised to see spikes in areas of the haunted home we toured in areas where there shouldn’t be anything detected, as well as fluctuations without moving the device.On top of that, we got evidence like whispers and sounds and footsteps at the same time as getting EMF readings. So that was very compelling.A great device for a fantastic price! Make sure to charge before you go investigate as I found it ran out even when it was turned off.

I bought this to make comparison measurements of permanent magnets for a project.The Instructions that came with it state that the lowest frequency for measurements is 5 Hz. Since a fixed permanent magnet is 0 Hz, this just wasn’t what I needed or expected. So I’m returning it.Wish the bandwidth had been stated in the description.It’s a nice unit though.
