EMF Meter, Hound-200 EMF Detector: 3-in-1 Portable Electromagnetic Field Radiation Detector for EF, RF, MF, WiFi Signal, Suitable for Home, Office EMF Inspections and Ghost Hunting - Green

I have heard about radiation and am so glad I bought this meter! I no longer wear my series 8 apple watch. I measured the radiation from my watch and saw it peak into the red from where it would touch my wrist. I learned that my apple watch would have to be about two inches away from my wrist to not give me dangerous levels of radiation. The watch has to have skin contact to give acurate readings. I tested my wife’s series 7 and it was okay, in the safe zone. I am only allowed one video so I also posted a picture next to my iPad. When I called apple, I was told that they are aware that a series 8 does put out more radiation, but is below government specifications. Using this meter, I made sure that there was no other devices nearby to affect my measurements. I measured without touching the meter. I did a measurement that can easily be replicated (repeated). I measured my watch as if it would touch the skin by placing the head of the meter next to the skin side of my watch. I also measured the top right corner of my iPhone close to where it would generally touch my ear. There was a corner where I get the highest reading on my iPad also. Using this meter, I discovered in measuring radiation from android type smart watches, all of mine were in the safe range. Unfortunately many watches are not as accurate in measurements as the apple watch. I learned that I had to be around 6 feet away from my microwave when running it. I did measure my wife’s Toyota hybrid, which read okay. I learned how far away I need to be away from my wifii router. This meter is very easy to use and understand. I like the peak measurement capability. The color schemes while reading are very obvious of green, yellow and red. I work at church in audio/ visual production and discovered that there are some dangerous hot zones that are dangerous to health. My sound booth had some eye openers. I now do my best to hold my phone away from my head, use speaker phone, and other adaptations. I severely limit my use of noise cancelling headphones. I pay attention about where my phone is away from my body. After not wearing my apple watch for two weeks, I noticed that my body did not ache as much and I was sleeping much better. My brain function improved. I now am sharing this meter function to show others the dangers of invisible radiation that affects one’s health. I am researching different radiation blocking devices, but I haven’t found anything that works. The two things from Amazon I bought did not work and one is no longer for sale. They had absolutely no affect on reducing radiation. I HIGHLY recommend that you buy this meter and USE it! Your health is at stake. I am so glad I bought this meter! It has changed how I live my life.

If you have ever wondered about EMF emissions from your appliances, cell phone, and other assorted devices the "Tesmen EMF Meter" will help you define areas where the fields are present. Based upon other reviews I was not surprised that the emissions around our kitchen microwave oven were very strong out to over 6 feet. Not surprising given that a 1000 watt microwave is basically a focused 1000 watt 2.45 GHz transmitter. I won't be leaning on the microwave cabinet the next time I warm up my coffee! The mesh router system in my house was fine as long as you don't park yourself within 1.5 feet of the router and access points. If you have any Wi-Fi components on your bedside table you would want to find another place for it. As mentioned by others our cell phones were not an issue while on Wi-Fi but when directly connected to a tower far more transmit power is used and it registered as quite strong. I do have a desktop stand ($12 here on Amazon) that I put my cell phone on that facilitates speaker phone operation and that guarantees operation from a safe distance. The manual is well written and covers every aspect of operation and function. It was a nice touch that within 24 hours of delivery Tesmen reached out through the Amazon messaging system to reinforce how to get started and how to operate the meter. They also encouraged the customer to contact them directly with questions or for additional assistance. Nicely done! Five stars for the Tesmen EMF Meter without any hesitation.

I haven't checked this meter against another one for calibration. However, its readings seem to make sense. For example, a laptop that is plugged in has a much higher reading than the same laptop running on battery power. The readings go down quickly as I move the meter away from a running appliance. And a cell phone with data turned on gives a higher reading than the same phone with data turned off. The batteries have held up for maybe over a year now (with just occasional use). The different modes are clearly detecting different things, because they detect higher radiation in different (but consistent) places. So although I can't say for sure whether the readings are calibrated right, they at least give me a good idea of how best to lower radiation exposure. The meter seems to work for what I bought it for!

The TESMEN EMF Meter, Hound-200 EMF Detector does what it is designed to do. It measures electromagnetic radiation. There are three types of electromagnetic fields: electric, magnetic, and radio frequency. Electric fields are produced whenever there is an electric charge present. So, an electric wire will generate an electric field whenever voltage is present in the wire. Magnetic fields are produced whenever there is current flowing through a wire. The stronger the current, the greater the magnetic field produced. Radio frequency fields (RF) are the high frequency radiant energy given off by microwave ovens, home WiFi, cordless telephones, and any other device that generates radio frequencies. The TESMEN EMF Meter measures all three of them. I cannot speak on its accuracy because I have no way of measuring its accuracy. In my home, there is a microwave oven, cordless telephones, and a WiFi network. I also have probably the average or slightly above average number of appliances running at any given time. My back yard also adjoins the electric company's right-of-way containing major electric transmission lines. So, there is a lot of EMF around my house to test. The most concern are the major electric transmission lines behind my house. During peak electric usage times (usually at night), the meter will light up red indicating high magnetic and electric fields when I am standing next to the electric right-of-way. But the fields diminish substantially as I walk away from the right-of-way toward my house. By the time I get up next to my house, the meter will show either green or amber. In my house, there is no appreciable RF present unless I stand next to the WiFi receiver. There is also very low electric field indications. Magnetic field shows mostly amber during peak electric usage and green at all other times.

Good quality, not too big not too small, comes with batteries which is rare, nice carrying case. Seems to work good easy to read, adjustable sensitivity only complaint is it beeps constantly not the best choice for ghost hunting

In October of 2024, I bought a new Samsung 24 (I forget what series), phone after my old one crashed. Immediately after leaving the store this phone made my hands and lips tingle, and actually burned my neck and ear a few days later. This phone got very hot and I could not hold it for any length of time. The same day I bought the phone I ordered this meter to test the phone. The readings from the phone pegged in the red, on the RF band especially. We used this meter to test all of our other devices, including the microwave, which we no longer stand in front of when it's in use, to get comparative measurements. We took the phone back to Verizon to exchange it taking the meter with us to demonstrate the emissions. Interestingly enough, the device didn't read anything while we were in the store. Not even my husbands' phone which was emanating in the red on the RF frequency occasionally. Evidently, there is something in the stores that mitigate the frequencies. We were told that some phones have "hot" batteries and we were given the exact same model. I experienced the same symptoms, but to a lesser degree and could only determine this after leaving the store. This phone too was replaced with a different model. This device was very effective for diagnosing a really bad problem. It let me know that what I was experiencing was a genuine reaction to a defective phone. I recommend this to meter to anyone concerned about the electronic emissions in your environment.

This device works great. I've used it all around my home and the worst is the microwave and phone. The phone is bad when on a call and running off cell towers. Online with wifi it's not bad. Those readings are on RF mode. Manual is very informative. I've always tell people don't hold your phone to your ear !! I know people that got a tumor behind their ear requiring surgery. Many fake blockers sold out there that don't work! My microwave puts off a bad RF up to about 8ft. I always figured a few feet away was safe, now I leave the kitchen. It's worth the investment. Power lines outside are bad if your under them. Remember the carrier not always gentle in handling electronics,they are mass producing everything. It's not always the makers fault if you get a bad one, don't get mad they will replace it...I do recommend this product..

It works! Just wanted to test equipment before purchasing it. If there were too many EMF’s I would of not purchased it. This is a good tool to have around.

Used to check the function of a wireless remote control. It proved the the remote was working fine but the receiver was dodgy.

Bought this to test out electrical products. Was really interesting. Was testing everything from our wi router, Alexa, microwave, mobile phone and wireless earphones (which I've now stopped using because I was surprised how much EMF they were emitting) I would say it's useful, easy to use, good quality for the price and good value for money. It opened up my eyes to how harmful everyday electrical items can be

When it comes to electromagnetic radiation, I often think of the movie Johnny Mnemonic. In our modern life, we are becoming more and more exposed to EMF. Wi-Fi, radar, radio, satellite, cellular, Bluetooth, electrical wiring, etc etc. I do hope it never comes to what is portrayed in the movie, but too much may not be healthy. The TESMEN instrument can detect electric fields (EF), radio frequency fields (RF), and magnetic fields (MF) per the listing. It is easy to operate having a few buttons at its base to turn on/off, silence the beeps, grab a reading, recall a max reading and of course, changing what field one is interested in detecting. The display is easy to read. The background changes from green (ok) to yellow (warning) to red (danger). The gauge on the display increases as the strength of the signal increases. The beeping becomes faster as well (like a Geiger counter!). The top part has a radiation symbol which pulses. This one appears to be just for show. I went snooping around the house with it to various appliances, electrical circuits, places where I knew there were magnets or wires, etc. While one could consider this an adult toy, it is practical. For example, Microwave radiation is something that could be harmful if one doesn't know there is an issue. The TESMEN comes with a nice hard shell case with a carrying strap. 3 AAA batteries are included - Duracells in fact (a rarity). My plan is to bring this out from time to time and 'snoop' around, just to make sure there is nothing going astray.

L'appareil permet de mesurer 3 types d'ondes. L'écran est très lisible et efficace facilitant la détection d'ondes nuisibles dans un local, une pièce ou l'entièreté d'un appartement (dans mon cas). Le boitier est bien éclairé et paraît assez solide. Un étui et 3 piles LR03 sont incluses.
