EMF Meter Model TF2 – #1 Handheld EMF Detector for 3 Types of Electromagnetic Fields: Radio (RF), Magnetic (MF) and Electric (EF) - Measure 5G, Cell Towers, WiFi, Bluetooth, & Smart Meters

I love this device. After reading information from the international meeting about Cellular radiation concerns at the Israel Institute for Advanced Studies and Dr. Devra Davis on breast cancer, and being a physician myself, I wanted to test my home and my habits. The device is easy to use— just put in the enclosed battery and turn it on. I found much to my surprise that my seat at the kitchen table was a hot spot for intermittent RF probably from my geothermal heating system just below the floor. It was very helpful to put the meter on my chest and watch the effect of simply moving my cell phone an arms distance away. Dittos for getting my husband to stand back 10 feet from the big OLED TV. ( Standing within two feet he was exposed to bursts of RF 5-6 times the federal maximum recommended exposure level. Now, sadly, this does not measure 5G but hopefully that technology will be available in the future. And when it is I will make sure to get this brand. The Company is awesome. I had my meter fall off my coffee table with a stack of papers and it hit just perfectly to maximize impact. It damaged the RF part of the device while the rest (electric and magnetic fields) were ok. I was sad but contacted the company. They promptly responded and coordinated return. They fixed it at no cost and turned around the repair in under a week. Best customer service you could want. You will a learn a lot by having this device in your life. We are being bathed in cellular radiation and as Dr Davis said, the same technique for denial of cigarette smoking dangers are being used to deny cellular phone radiation danger. I live daily with Ionizing radiation as an Orthopaedic Surgeon, and I’m not unreasonably paranoid, just reasonably cautious. I am a member of the first generation of humans to be bathed in radio waves and now we are going to be subjected to MICROWAVES. It is a great experiment on human physiology. This device helps you monitor and mitigate your exposure.

I bought this Trifield meter because it came highly recommended by several social media sources.I've wanted one for a few years and just made the decision to buy it.All, I can say is, "Wow! What an eye opener!". It's like having a new set of eyes, seeing things you couldn't see before!I measured around my work table. There was a lot of RFs coming out of laptop but you had to get really close to the screen or keyboard. At normal viewing distance, the levels were "safe" (0.20 mW/m**2) according to their documentation. Of course, you need your hands to be close to the keyboard to type but that can't be avoided.My router surprisingly had very low RFs coming out of it but I had always adjusted the router to put out 25% output power in it's settings. No need to blast my wifi to my neighbors.What really surprised me, was my table lamp was putting out massive RFs! It was well above the normal safe levels if you're close to it. I normally have it about 2 feet away from me which brings the RF level down to safe. But sometimes, I bring the lamp close my head when trying to read small writing.What's also very surprising is the amount of "unsafe" RFs coming into my bedroom window! I did similar readings from other windows and they are at "safe" levels. It's only "unsafe" from the one side of the house where my bedroom is located! As suggested in the documentation, I put up some aluminum foil on the bedroom window and that dramatically reduce the RFs coming in. I should mention with the meter, I could tell the bedroom wall was also blocking some of the RFs but the foil was more effective! That was interesting to know.The meter itself is sturdy and well built. It comes with its own case. There's a pamphlet and fast startup card as documentation.People complain about the backlighting and sound toggle buttons being in the battery compartment but it doesn't bother me at all. I have the backlighting always ON and don't use the sound. I don't have the battery popping out problem. Maybe it's because I bought it new.I've read conflicting reviews, 5 stars and 1 star, from people who say they are electrical engineers. Some say this meter is good and others say it's junk. It's hard to judge who is right. This is my first EMF meter.For my purposes, it works well. Using my "new eyes" analogy previously mentioned, I just need to detect an unseen light is there and that it's strong enough to hurt me. I don't need to know the exact details of the light. I need to know how I can weaken that light and be able to detect it's now weaker and at safe levels.
