EMF Detector, Detect All 3 Types of Electromagnetic Radiation Field in 1 EMF Meter for Cell Towers, and Smart Meters, EMF Reader for Home, Office (RD630W)

Veru good

This thing is actually detecting all three different measurements consistently. It works well.

Works great

Funciona perfecto

Functions well and easy to read. Good value for personal use Battery wore out relatively quick, but it was put through rigorous testing of various homes. Like the 3 color, bright display. We used on all the appliances and electronics to determine dangerous frequencies and the range to which they extend.

A concerning, but widely unknown fact is how strong cell phone signals, Wi-fi, and electromagnetic fields have become over the last three decades. As any competent Biology professor will tell you, a human body is an electro-chemical machine utilizing electrical impulses through nerves to move muscles, feel pain and pressure. Chemical actions within a body regulate cellular activity, hormones, break down food consumed into usable components, etc. Interference with those vital function can and do cause problems.Keeping all this in mind, Cell phone signals and Wi-fi utilize wave energy to operate. Wave energy can range from microwave, x-ray, radio waves, infrared and ultraviolet waves, essentially across the entire wave spectrum. For example, a Microwave oven uses microwave energy to make molecules vibrate rapidly creating heat, that cooks food, such as 'meat' etc. Meat is 'muscle' tissue. The metal sheet with small holes in the glass of a microwave creates a 'Faraday shield' through which microwave signals cannot pass.As the wave strength of Cell phone signals and Wi-fi increases, the potential for disruption in Human cells increases exponentially. This is also true for Electromagnetic fields. Computers generate powerful magnetic fields. The strength of these fields decreases rapidly over distance, so the closer to the source, the stronger the magnetic energy.Cell phones contain very powerful, miniaturized computers! They therefore create powerful electromagnetic fields.This device/tool can measure the strength of all these wave signals.Now, the eye-opening part. Turn the device on while standing away from your cell phone, W-fi router, laptop, or Apple computer. You will notice that the various type of signal strengths displayed on the meter either reads zero, or very, very low from background sources.Then move the device closer and closer to the cell phone, computer, router etc., and watch the numbers (signal strength energy) skyrocket. As those numbers increase a series of lights change from green to yellow, and the red light meaning extremely powerful.I have measured my iPhone 15 Pro, our whole house Netgear router, and pc.For all of them the signal strength goes 'off the charts' as you get close. Within two to six inches of the cell phone the cell signal, microwave band, and electromagnetic readings are alarming! The other devices are the same - alarming.Imagine the potential harm these can do to at the cellular level in your body (such as your brain), if held close for extended periods of time, or continual exposure such as having your phone on your hip all day, or in your pant pockets, close to reproductive organs. Think microwave cooking type damage.The GOOD news, this meter can detect the distances at which the signals can be dangerous, AND Faraday cloth, or blankets can totally block all these signals. Do some research and get some of these Faraday shield materials to protect yourself, and your children.There are many types of Faraday shielding materials such as very light cloth, and blankets sold on Amazon. A word to the wise . . .

I figured for 25 bucks I didn't have much to lose so I rolled the dice. I have a $200 Cornett meter which is very accurate (I've tested against similarly priced TriField and Safe and Sound meters). This meter is just totally hit and miss. It's weird, because SOMETIMES it registers the correct amount of RF (more or less), but then other times it just shows 0 when there's DEFINITELY a lot of RF. It seems like if there's a VERY HIGH amount of RF, it will register, and then if you back away it seems to slowly drop down more or less accurately. But if you start from a lower amount (let's say 3mW/m2 - which, by the way, is still PLENTY to cause health issues), it will frequently just not register anything at all. It almost feels like, if you can imagine this, a sensor that's "sticky" - like, it takes a bit to "move the bar", but then in will "get stuck". I guess this is just what you'd expect from cheap electronics/sensors. It's a shame, because I like the interface idea with the color changing, but the problem is, it just doesn't work. Worse still, it will undoubtedly give people a false sense of safety because it doesn't register RF that is most definitely effecting them. So you can hold it up and say "see, this room's all clear" when it's NOWHERE CLOSE. So yeah, if you want to hold it RIGHT NEXT to your WAP, or your phone that's currently on an active call, it will show RF - but DUH - of course we know there's RF coming from these devices. The problem is thinking that lower amounts of RF just don't exist because this meter doesn't show it. So as a "fun gadget", I guess this is sort of functional - sort of. But if you're really looking for a device to show you what's ACTUALLY going on with the EMF in your environment, forget it - absolutely worthless. I'd like my 25 bucks back but it's not worth the trouble. Lesson learned. You get what you pay for.***UPDATE*** - The vendor has contacted me and not only offered a refund, but also an upgraded model, which I'm told has better accuracy. One I receive the new model, assuming the accuracy is in fact better, I will update this review again. Definitely please with the vendor's excellent service!
