TESMEN 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 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!

Works!! Still playing around with it but definitely went off the chart around our wireless router. Very easy to use. Good value.

Part of the issue is that I don't know much about types of radio waves or radiation. Our microwave appeared to be faulty. The (Panasonic) unit would operate when the door was opened. I didn't know if it was emitting radiation when this occurred, which is why I purchased the detector. It looked good, but the instructions were limited. I thought the light at the top of the unit would indicate the detection of harmful radiation. It doesn't. The display does change from green to red when high radiation is detected. Apparently it is just for decoration. I did show radiation being emitted when the door was open. No leaks when the door was closed. Some research indicated that a switch was probably the issue, but that a qualified technician should address the issue, due to voltage that might be retained in the system. Also, it looked to be difficult to get into the area where the door latches. We bought another microwave, as repair cost would likely exceed the cost of a new unit. Regarding the meter, it seemed to do its job, but the weak instructions caused me to not give it the highest rating. If I were to need to check a microwave for leaks again, I would buy a simpler unit.

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.

Arrived as described. Worked well!

Sehr gut handhabbares Gerät, dass reproduzierbare Ergebnisse liefert. Kaufen, wenn man es braucht.

Buen medidor

Rispetto ai vecchi modelli ha una marcia in più oltre che a essere più affidabile e preciso.ottimo acquisto!

Shipping Packaging was good. The Tesmen Hound-200 is a good investment for individual use. I have searched Third Party Testing for this device and it's calibration is bang on with EMF readers that cost 10x as much. If your looking to safe guard your health this is a great investment.

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
