    Best Smart Health Tool on the Market!
    Boy is this handy & informative Very Smart Health Tool to have. Especially if you are on the OptOut list from Smart Meters! It helps you locate & measure any EMFs in & around house, property, neighborhood, electric car(!), office etc. Really glad we chose this one , as will accurately measure any EMFs including dirty electricity of improperly ir old wired homes, radio frequencies from Smart Meter, smart phone, smart appliances etc. To test: Turn on (will be in the emf read mode) & put up to utility meter level at the dark aperture slot. If it immediately starts beeping & flashes red (danger levels), then set it onto RF, will give you more particulars & a graph readout. Then can test up to 5 frequency ranges. Can save data & transfer to computer. Elster AB1 analog faceplate electro-mechanical meters are ‘stealth’ meters. According to Honeywell the “Elster the AB1 analog meter, can conveniently be initially or retroactively easily outfitted with communication capacity, 1 or 2 way.” [=RF chips].

    Extremely versatile and useful at a low price. Outstanding value
    This unit is amazing There are several screens to see EMF, EM and RF. One screen shows all 3 at one. Another is a graph show the quantified amount of EM and EM. But what we found especially useful that was not clear to me when we purchased it is the screen that shows and can document the frequencies and thier dBms hitting your home. With triangulation you can locate the origin signals, UMTS towers included. It will track all your data, the only cavet is that a Microsoft operating system is needed to track data. We had experts come to check our home with the expensive spectrum analyzer. He was very taken with this unit. It is so useful!

    “Advanced Radio Frequency Detector for Accurate Signal Detection”
    I recently purchased the radio frequency detector, and it has been an outstanding addition to my toolkit. This device is incredibly sensitive and accurate, allowing me to detect and locate various RF signals with ease. The user interface is intuitive, making it simple to operate even for someone who is not a tech expert. The build quality is robust, ensuring durability and reliability in different environments. Whether I’m troubleshooting interference issues or ensuring the security of my communications, this RF detector delivers excellent performance every time. Highly recommended for anyone needing a reliable and efficient RF detection solution!

    Functional & Value For Money
    Like – Can check and display ef, emf and rf at one go and easy to read. Not pricey like most other makes.Dislike – A bit flimsy to hold at bottom end. Some instructions are unclear – like how screenshots are taken and retrieved.Uses – check radiation on cellphones, wifi router, main meter, power points and home environment.

    Nice features
    Easy to run and long battery life.I did not realize how much RF, and EF, we are exposed to.Its a nice little device to see how to avoid long term exposure, and what to avoid.My cell phone is not sitting next to my body anymore for any long term time, I could not believe how high the RF is when connected to WIFI or the tower..

    Easy to operate and lots of features
    I saw a review by a Phd EE involving this meter and comparing this meters’ performance against other popular meters of similar function and one thing this meter was superior in was detection of extremely short pulses and decided I wanted to buy it. Upon receiving the meter I was surprised to find out just how much it was capable of and was glad I made the purchase. It has a lot of features and is very user friendly and easy to operate and set up in my opinion. It has already clued me in to some noteworthy activity as well. This meter is an excellent value for the money and you will be glad you bought it. A very good value!

    Fantastic and useful!
    I love this! Had multiple possible sources of EMF in the house and neighborhood and wanted to get a reading on just how much. Incredibly useful and fun to use! Might take some practice to understand all its features, but once you do it’s worth it. You get what you pay for, in this case a high quality and practical device! Also the battery life is insanely long.

    This meter is half the price of equivalent competitors and provides everything a budding home worker or concerned parent could possibly need. Easy to use and sensitive enough to be able to easily sense check that the meter readings are reliable (which they are with mine). Super accurate in fact, especially when held correctly (as shown in small printed instructions). I wanted it to check my home office and particularly the electric / electromagnetic field fields and radio frequencies (aka WiFi exposure) at my desk & kitchen table (for home working under lock down). With some small changes was able to reduce our exposure to all forms of invisible radiation by more than 10 times. Also was able to see change in RF in real time as I used WiFi on my iPad. I already knew that you should not hold your iPad in your hands and use WiFi but the results were an eye opener. Needless to say my desktop computer is not connected by Ethernet cable and favoured (whenever possible) over the iPad. I have also move the modem (which is really harmful at short range, shit these things should come with a serious health warning!) as far from me as possible. This device is a God send and only after I had bought this meter did I watch ‘Better Call Saul’. So glad I went for this meter and would recommend to anyone remotely concerned about their health with all the debate raging over 5G

    高エネルギーの充電式リチウムイオン電池が使用されています。電磁波過敏症の重症者は、充電式リチウムイオン電池から放出される低周波電磁波で病状が悪化しかねないので、お勧めしません。高周波と低周波の両方を測定できるなど性能はよいので普通の人には問題ないと思います。

    Lo he utilizado únicamente para medir la intensidad/densidad de las ondas electromagnéticas emitidas por una cocina de cuatro placas de inducción (para ver si podía cocinar sin riesgos después de la implantación de un marcapasos). Y el aparato ha sido muy sensible en la medición, diferenciando claramente entre lo emitido por cada una de las cuatro placas, así como mientras me alejaba/acercaba de cada una de ellas.Inconveniente menor: el manual de instrucciones no viene en español/castellano.

    Used this clever detector to pinpoint location of upstairs neighbour’s router which I discovered was beaming down unacceptable levels of emf on my sweet little face as I slept.So I pinned about 80 square feet of thick aluminum BBQ foil to the ceiling in the specific area of maximum intensity. That totally mitigated it.Flatmate ordered new tv/wifi service, and they brought in a fancy new router claiming it is soooo fast and wonderful. I tried the service out with my ethernet and it’s no faster than the previous router. But now emitting MASSIVE! EMF. The obnoxious installer is literally kneeling over the powered up router for half an hour working away while claiming It’s an insane conspiracy theory that these routers are even mildly dangerous.I certainly hope this installer doesn’t get testicular cancer…As soon as he left I put the router in a crude Faraday cage in the form of a loose lidded turkey cooker. The emf levels dropped down to sane levels, and somehow roomate’s wifi still works perfectly fine even through this metal cookerAlso found big EMF spikes at traffic intersections. But that has ABSOLUTELY NOTHING! to do with all the vehicle accidents and spaced out drivers seizing up and flattening poor pedestrians on the crosswalks these days.All in all, this device gives a person an idea of what’s going on.
