EMF Meter 5HZ-3.5G, Vlifree EMF Detector with Digital LCD Backlit Display for Electromagnetic Field 5HZ-3500MHz, Electronic Radiation, Temperature Detector, EMF Tester for Home, Ghost Hunting

For the past six months I have had this huge problem with local power company FPL, so around four months ago I purchased this gadget, and was able to precisely pinpoint the problem, which it was great accomplishment, and the rest was done by this professional company, nevertheless although this item not a professional device, it definitely did the job and I'm very happy for that .

One of my paranormal research teams favorite tool. We use this all day long while ghost hunting, and the battery life is decent. The beep tone is loud, lights change color, and temp guage is quick and accurate.

I put the battery that comes with the unit in, but it failed to power up other than a temporary blip. Tried putting it back in a few times, but still nothing. Put a new battery in, worked fine. So, make sure you have a spare 9V battery if you purchase this item. It's actually very good for the price.

There were other reviewers who reported that theirs did not have temperature readings but mine did. I can even toggle between Celsius or Fahrenheit.From looking more closely at the other reviews, it appears that there were 2 models: the one that I got has the straight antenna and this one has the temp probe. The other one has a round ball antenna and that one does *not* have temp.Also, the screen has the capability of backlit which also toggles on a LED flashlight on the back side.Overall, seems to work though sensitivity and accuracy is questionable as it did not detect any EMF on my iPhone X when I scanned it like in the ad’s video. It did however detect the microwave.Build quality is excellent which was surprising for being priced at under $20 at the time of this writing.I don’t know the accuracy but what I can say is that when I turn the microwave on and move this device close to it, the meter goes off the charts with an audible alarm and a flashing LED light on the antenna (goes from green > yellow > red as it is moved closer to the microwave)

I like:-The green/yellow/red light on the antenna.-Came with a good, simple instruction manual.I dislike:-That it shows 'OL' overload constantly.-It overloads at around 20uT whereas my other, slightly cheaper meter goes up to 190uT! Yes uT and not MGs. Once this meter gets to 5uT it will kump to 19.99uT and OL... constantly no matter where you point this. OL everywhere, while my other meter reads 4-6uT this goes to OL. You can set this to MGs but basically same results: OL everywhere all the time.-Around 0-5uT it matches the other meter, but then shows way different and then 'OL'. So it's not really able to give you a reading, just 'OL' almost 90% of the time. It was hard to find any room where it wouldn't just OL immediately.-Turning on the screen backlight ALSO turn on the flashlight on the back. Annoying in some cases, especially if you're working around other people.-I'm giving this away to a "ghosthunter" since it's useless for my more traditional uses, but I feel they'll end up putting masking tape over the flashlight so as not to spoil the atmosphere in a dark and spooky place, lol!There are cheaper meters without the antenna that work better for all purposes.

Works great

It seems to work fine except the reading updates are very slow. You can't sweep it around looking for changes. You have to pick a spot and wait for the update.

I love the simplicity here. No hard instructions & it really works!
