ED88T Electrosmog Detector by Cornet: Monitor and Protect Yourself from Unsafe Electromagnetic Fields

JJJ: 簡易的な周波数カウンタとして買いましたが精度悪いです。300MHz帯で500kHz程度の誤差あり、感度もよくないです。100mW程度の出力だとアンテナと本体密着させても安定しません。多機能ではあるようなので値段はお手頃なのかもしれませんが説明書が英語なのでよくわかりません。

Jason R.: This product was recommended by Nicolas Pineault from the Non-Tinfoil Hat's Guide to EMFs partly because of the audio signal/feedback. I assumed that I should hear something when the wheel is moved to turn it on. I get NOTHING. NO SOUND. Definitely not worth buying. DO NOT recommend. Also it says NOTHING about 5G so I assume it's now useless as 5G rolls out all around me.

Helena Loges: I have to first mention the incredible customer service provided by this company. We are going out of town and were concerned about receiving this product before we left, and they assured us we would have it right away. We had no idea they would get it to us the very next day! Thank you so much!
Due to the coronavirus and the need to work from home, we had to upgrade our home Wi-Fi from 20mbps to 100mbps. This has caused our family to have headaches, joint pain, and skin and scalp burning. We needed to measure the RF field to see what we were exposed to and we were shocked. According to building biologists, anything above 1.0 mW/m2 is an "extreme concern". Our Wi-Fi router gave us an RF reading of 546.0 which is 546x above the "extreme concern" level. No wonder we have been suffering! We also measured the gauss of our microwave, which was extremely high (We won't be using that anymore), and we tested our electrical outlets with ELF mode on the Coronet, and found wiring issues in our bedroom and master bath. I cannot recommended this product and company enough! Every home should have one!

R. Mcdonald: Great product. I've only used the RF setting to measure cell towers, cordless phones and cell phone radiation. It is shocking to see just how much radiation these things emit. I have already made changes to my living space to make it much more healthy and safe.

FG: Great entry level product, multi-purpose, allowed me to find neighbours Wifi, hidden power cable in the wall, help friends find their EMF/RF sources. Highly recommend. Fast shipping. A+

aman: This is a great device to have. I have learned so much about the RF pollution in my home and office. The only reason I gave it one star less than perfect is because of the super cheap quality plastic that they use for the outer casing. I accidentally dropped the unit two feet from the desk onto the carpet and the power button fell off. The Cornet company could easily invest in a higher grade plastic for the chassis and buttons, and pass the extra cost on to the consumers. I imagine that most consumers would gladly pay the extra few bucks for a more durable product.

Wendy: This detector does the job I needed it for. It was here exactly when Amazon said it would be. Very happy so far with it. Thanks

Amazon Customer: Educate yourself on how to use this meter and what it can show you before you try using it and you will find it an excellent tool for your home and office.
Use it to understand what you do in your daily routine that exposes you and those you share a home or office with to unnecessary and potentially harmful levels of electromagnetic radiation. Yes, the studies about cell phones, tablets and the countless wireless devices we use in our every day lives are telling you "no direct evidence of health dangers have been determined yet" and "additional studies are required". Actually some of them even warn you in the fine print that nobody reads that you should use several inches or even feet away from your body.
It will take decades before these conclusive studies are conducted in a way to convince the powers that be to enforce strict standards to technology giants making enormous amounts of money from these devices.
Meanwhile, you and I and our families will become part of those statistics. OR we will open our eyes today and make those necessary changes to at least minimize our exposure where we spend most of our time, like at work and at home. Do you really need your wifi on...

Kevin: I love this meter. It's easy to use and does a great job of helping me know when I'm exposing myself to too much unnecessary electrical and magnetic radiation. Using this meter I moved things around my office without too much trouble so that now I sit all day in a green safe zone instead of a yellow zone. This meter showed me for example, that my laptop was safe 8 inches away in front of my hands and the external keyboard I've been using for years has been a good thing. My large computer monitor shows safe if I stay at least two inches away from the front of it--which I always have, but at least now I know that the flat screen monitor technology I've been using all these past years has been safe, and that's a relief. The biggest emitters of electromagnetic radiation were the power adapters, and they are all away from me. The laser printer was sending out a powerful yellow spike every ten seconds over wifi polling the network, so after seeing this, I made the decision to leave it turned off until I need to print.

This meter showed me if I wanted a subwoofer in my truck I would be sitting in a yellow zone instead of a green zone, so I pulled out the battery lead from the cab...
