RDINSCOS EMF Detector 3-in-1 Electromagnetic Radiation Meter | Handheld EMF Detector, for AC Magnetic/Electric/Microwave. Ideal for Home, Office, Smart Meters & Non-Professional Users

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 Mutes 2nd Long press turns off backlight completely (Display still functions/visible) 3rd Long press unmutes 4th 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 settings 2nd Short press turns off HOLD function, numbers return to normal scanning 1st 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 function Now 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.

I bought this for work, but these are cheap insurance to see where the EMF radiation hot-spots are in your home. You don't want anybody's bed or sofa to be up against a wall where the signals are high- not just from cell towers, but electrical currents from wiring in the home- it will cause harm over time. Check anyplace you spend a good amount of time. Either relocate that bed, or create some space between it & the wall- an extra foot makes a difference. If you don't have a lot of options, make sure your head is at the safest distance.

Let me start by saying this is the first EMF reader I've ever purchased. It's eye opening to see how much radiation is happening on things that I would have never known. There are definitely better quality ones out there, but for the price point I'm very happy with my purchase. Who would have thought my feral cat house was giving off this much radiation even when it was off? And that my air purifier was getting off radiation even when UNPLUGGED! I looked it up and my Wi-Fi router throws off frequencies and the purifier picks it up (they were pretty close together). Now I'm able to make necessary changes, like a battery operated clock next to where I sleep instead of one plugged in. It's amazing how many things are giving off frequencies. And how the smart meter throws it off through my wall from the outside. EMF definitely affects us. My naturopath doctor wanted to rent me one for $50! Now I own my own for under that. I'm still learning how to use it. But if you're looking to identify harmful frequencies, I definitely recommend!

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!

I've been using this EMF meter around my home to identify and compare various electronic devices. The display is easy to read, measurements respond quickly, and the controls are straightforward to use. It has been interesting to compare different appliances, routers, and electronics around the house. The compact size also makes it easy to carry from room to room. Great tool if you're interested in measuring electromagnetic fields around your home or workspace. Used over one week to evaluate ease of use, responsiveness, and overall functionality.

This was super helpful — I was able to isolate all the radiation EMF trouble spots in my home. I did buy a beanie that has barrier material in it to protect my brain. My CPAP went off the charts, the bad headaches that I had from the CPAP and other EMF once I isolated where it was coming, and I found the remedy in the protective clothing and moving my technology around things have really improved.

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!

Un equipo de buena precisión que da tres lecturas simultáneas de variables con niveles de alarmas visuales y auditivas a un excelente precio.

Franchement, ça fait le taff ! A utiliser avec une perche isolé, sinon en tenant l'appareil en main, la mesure est faussé !

Worked perfectly for the measurements I needed to take. I was most surprised about the EMF field around extension plugs. The magnetic field around them is incredibly powerful so be mindful if working near one like I do. It's easy enough to use and decent quality so value for money in my opinion compared to some of the other options on the market and silly money.

Nooit aangekomen, gelukkig wel geld teruggekregen.

Strumento curato, anche nella confezione e nel manuale di istruzione in italiano, inglese e tedesco. Provato in prossimità di una linea elettrica a 380 kV ha dato le misure ragionevoli, sia per il campo elettrico che magnetico. Anche un prossimità di un monitor LCD consente di individuare la posizione del trasformatore switching. Anche la parte RF pare funzionare, ma non ho potuto fare confronti. Ho preferito questo modello 630W con batteria a 9 V (fornita) rispetto a quella ricaricabile, perché comunque lo userò poco e la preferisco sostituibile. Aggiornamento Confrontato con uno strumento professionale dal costo 10 volte superiore, mostra valori del campo elettrico molto simili, per quello magnetico molto simili ma solo a partire da intensità superiori a 150-200 nT, mentre per valori inferiori la lettura scende rapidamente a zero, anche per campi dell'ordine dei 100 nT. Questo strumento fornisce una lettura isotropica del campo magnetico (mediando sui tre assi), coerentemente alla struttura dei sensori, uno per asse. Lo strumento professionale di confronto invece fornisce la lettura su un unico asse. Il giudizio rimane molto positivo, ma va evidenziato che campi deboli, seppur in teoria misurabili, non vengono visulizzati. Considerando che la soglia di attenzione è 200 nT, lo strumento rimane utile. Allego foto di confronto del campo elettrico e magnetico, e una dello strumento aperto che ne mostra la struttura.
