RDINSCOS EMF Meter RD637 – 3-in-1 Electromagnetic Field Detector for Electric, Magnetic & Radio Frequency Radiation, Real-Time Monitoring, Tri-Color LED & Audio Alarm for Home, Office

Great Product found many appliances with high emf readings in my home. I was able lower the radiation levels.

pueden mirar los videos del emf detector, me parece bastante bueno y funcional, y facil de usar.

Buy this, run it thru the house. Make a phone call with this thing next to it. You’ll never hold your phone up to your ear again. It’s amazing what some distance does to exposure.You’d be amazed at your exposure in front of the microwave, TV, lights, etc.I’m annoying to those around me with awareness of exposure before owning this. I’m sure to get even more annoying.Fear not. Be informed. Stay away from the herd. “Annoying” may save your family’s life.

Does not work. I tried this after using my buddies emf reader and it gave me no signals. Which I know is not accurate since my buddies gave me readings. I know it wasn't a units issue because I swapped units to check and it did nothing. To give an example my friends device registered my wifi router high (expectedly so) at about 8-12 inches away. This thing gave no reading until I was literally touching the router. You get what you pay for I guess.

I question how useful this EMF detector will be for most people interested in getting it.First off, if you’re getting this as a “ghost detector,” be aware that, per the instructions, you have to be holding it to get readings. So you can’t just turn it on, set it down, and wait for something to wander by. I suspect that most people who want to do a little ghost detecting want something they can set in a problematic spot, leave the room, and see if the alarm goes off at some point. You can’t do that with this. Plus it automatically goes off in 15 minutes, so your ghost better hurry up and make its presence known.Also, it can’t detect the radiation from cell phones and similar devices. It can only detect the radiation from cell phone *towers*.I picked up kind of alarming readings near my notebook computer and microwave, not entirely surprising, but then it also showed quite high levels just near an ordinary LED light strip. It was alerting near virtually every electrical device.I’ll have to read up more to figure out if any of this is valid.

This works just as good as an expensive one and it's easy to understand I love it

Not super sensitive but a good indicator of where radio frequencies are coming from. All my friends have borrowed it and thought it was very interesting. Glad I purchased it.

Definitely a must have.
