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)

Best purchase I’ve made in a long time. Works perfectly and easy to operate. Learned a lot about unsuspected emf emissions in my house including a digital clock and two bedside lamps that I loved and used constantly that were touch-control with 3 brightness settings and now I know emitted too much emf. I’m trying to figure out if there’s a way to use them going forward or just pitch. I wrapped my iPhone with 3 layers of aluminum foil underneath its case which alleviated almost all emf emissions and my neighbor came over with her iPhone and we tested it with this emf/rf detector and it went crazy. I offered to loan it to her to test her own household belongings and she replied she didn’t want to know what’s lurking there. I’m going to order one of these for my daughter so she can also choose how safe she wants her surroundings to be with all this horribly unhealthy modern technology invading every aspect of our lives we’re unaware of.

Works great and such an affordable, educational tool! I showed all 4 of my young adult and teen children some concrete evidence of what I've been telling them for years but they didn’t believe me or thought I was exaggerating. Now they seem to believe me that cell phones and microwaves emit things that are pretty bad the closer it is to your body. I don’t regret this purchase in the slightest ;)

I recently purchased the EMF Detector to assess electromagnetic radiation fields in my home and office while I tinker on projects. Here’s my experience with the product:Timely Delivery: The product arrived on time, which is always appreciated.Packaging: While the package was slightly damaged, the device itself was unharmed. It would be great if the packaging could be improved to prevent any damage during transit.Battery Reminder: One thing to note is that you’ll need to buy batteries separately. Make sure to have them ready when your EMF Detector arrives.Color Display and Measurement Options: I really like the different color display on this device. It’s easy to read, and the ability to change measurements (e.g., milligauss or microtesla) is a useful feature.Alert Indicators: The color-coded alert indicators are a standout feature. Here’s what they mean:Green: Everything is good and safe.Yellow: Elevated readings—be cautious.Red: Dangerous levels—leave the area or take additional safety measures.Multiple Uses: I purchased this tool for various reasons:Setting up a temporary Faraday cage.Measuring homemade antenna functionality.And, of course, ghost hunting in my house!Overall, the EMF Detector has been a valuable addition to my toolkit. It’s reliable, easy to use, and provides essential information about electromagnetic radiation. While there’s room for improvement in the packaging, the device itself performs well.I hope this review helps potential buyers make an informed decision! 👻

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.

Seems to work well. Super easy to use. The Red Yellow and Green displays are bold and easy to tell when you're near something bad. My GF and I went through our house and located several questionable devices which we moved farther away from areas we spend a lot of time. I am surprised people rate it due to the cheap 9-volt battery which is included -- the included battery worked but it's a low quality battery -- buy yourself a good Alkaline 9-volt and be done with that problem.You need to HOLD the unit to get accurate readings, can't just sit it on the table and let it go, it won't work correctly like that.We value our health and this looks important. Our worst offending EMF was coming from Thunderbolt connectors (yes the plugs) and from cheap DC USB chargers, one of which was very near my wife's head when she's sleeping. All the electronics have been moved away from our bed :)Wishing you all, low EMF days!
