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)

UPDATE~~~~~~~I've been "playing" with this some more. Couple of things I discovered. One time I powered it up and the backlight was non-functioning. I wondered what I had done???. Turns out the Power/Mute button does 3 things. short press turns the unit ON or OFF.1st Long press Mutes2nd Long press turns off backlight completely (Display still functions/visible)3rd Long press unmutes4th Long press turns on backlight (green/orange/red now effective)The Hold/Max switch (this is documented but not very clear)1st Short press turns on HOLD function and holds the current settings2nd Short press turns off HOLD function, numbers return to normal scanning1st Long press turns on MAX function, instead of numbers fluctuating up and down the MAX simply holds the highest value reached (once it stops changing, that's the max value)2nd Long press turns off the MAX functionNow a quirk. Safe (green), Alert (orange), Avoid (red). I started looking around at other devices and checking online for what are recommended "safe" values and that produced a number of different sites showing various ranges. I then discovered that the ranges are also variant depending which country you are in!!! Amazon has other EMF detectors which trigger Alerts at lower ranges than this unit. Some have ranges starting at .001 and even .0001 and max values way beyond the Alert triggering levels. Indeed this unit has max ranges way above it's triggering "Alert" values. Not sure where I could test this to reach a MAX value and not sure I want to be that close or around such devices anyway!!!So I guess the point I'm making is that for me, the range values are not so important because who knows what really is "bad" vs "good" numbers. If this unit beeps fast and turns red, I simply don't care what the number states on the display.. Clearly that's a problem. Even if it slow beeps and is orange, I'm still concerned. What I'm really using this monitor for is identifying how close do you have to be to items that start the counters increasing and identifying places where the device registers zero or close to when green. Basically, I can easily get the unit to register Alert by having the monitor touching certain devices (including the microwave). What I'm learning is don't let kids put there face up to things without first checking what is a safe distance for them. I don't intend to sleep on my microwave but I am also surprised how much energy the darn thing radiates when it's on. I'm also concerned about my mobile phone and how much energy that thing is putting out... So I do not use the phone next to my ear, nor do I use wireless ear buds... I have gone with wired because of the radiated numbers I get.I still cannot validate the accuracy of the unit. I have 2 other older devices and all 3 seem to give slightly different numbers. However, do I care which one beeps at what number? Nope... I simply know that all of them go crazy when next to Routers, TVs, LED bulbs, Microwaves, etc etc, and all stop when I move inches away from the device. I've no intent on sleeping or resting my head on any of those devices whether they are powered up or not!!! What I still like about this unit is the HOLD, MAX, triple onscreen display, the audible alerts and the visual color alert. The ability to turn off some of those features is nice but not essential in my usage.I still recommend this.ORIGINAL REVIEW~~~~~~~~~~~~~~I particularly like that depending on which tester exceeds various limits, the display will change from Green to Orange to Red. Readings seem valid but I have no way of verifying if the displayed readings are accurate or not. None the less, it does give readings that help identify concerns. Like for examples, safe distance from a Microwave, just how much RF energy is in the room with all the 5GHz RF in the house!!! I also tried it with my Samsung Phone and as I've always known for years, stick that mobile phone next to your ear and you WILL get a dose of RF.. That's why I only use the speakerphone or a I'll plug in a cabled headset!!!So it's a fun toy if nothing else which regardless of the accuracy of the readings (which I'm not questioning), does highlight things in the house that you should be aware of that give out energy that might not be good for you.

Veru good

Works great

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 . . .

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

Funciona perfecto
