TriField EMF Meter Model TF2 – Made in USA - #1 Worldwide Handheld EMF Detector for Magnetic/Electric/Radio Fields with Unlimited Free Support in the U.S. to Help Solve Your EMF Problems

I really like this meter. Seems to be very accurate. One thing that would be great if they would add would be some kind of an ability to look at history. RF frequencies are very difficult to kind of track down and they come and they go. One thing that this does, it tells you the peak and then it also tells you the average, which is very helpful. But when when the levels change so much it can be a little overwhelming to get a handle on it so that’s why I suggest some kind of a history where you could look at maybe a period of several minutes and take the average over that timeframe. Download it and analyze it. But other than that, the device is great. One other thing I would suggest to the company is that they add some kind of a handle or a grip to the to the meter because it’s a little slippery and I have to be careful that I don’t drop it. There’s a few other minor things but overall I think it’s a great meter.

I bought this Trifield meter because it came highly recommended by several social media sources. I've wanted one for a few years and just made the decision to buy it. All, I can say is, "Wow! What an eye opener!". It's like having a new set of eyes, seeing things you couldn't see before! I measured around my work table. There was a lot of RFs coming out of laptop but you had to get really close to the screen or keyboard. At normal viewing distance, the levels were "safe" (0.20 mW/m**2) according to their documentation. Of course, you need your hands to be close to the keyboard to type but that can't be avoided. My router surprisingly had very low RFs coming out of it but I had always adjusted the router to put out 25% output power in it's settings. No need to blast my wifi to my neighbors. What really surprised me, was my table lamp was putting out massive RFs! It was well above the normal safe levels if you're close to it. I normally have it about 2 feet away from me which brings the RF level down to safe. But sometimes, I bring the lamp close my head when trying to read small writing. What's also very surprising is the amount of "unsafe" RFs coming into my bedroom window! I did similar readings from other windows and they are at "safe" levels. It's only "unsafe" from the one side of the house where my bedroom is located! As suggested in the documentation, I put up some aluminum foil on the bedroom window and that dramatically reduce the RFs coming in. I should mention with the meter, I could tell the bedroom wall was also blocking some of the RFs but the foil was more effective! That was interesting to know. The meter itself is sturdy and well built. It comes with its own case. There's a pamphlet and fast startup card as documentation. People complain about the backlighting and sound toggle buttons being in the battery compartment but it doesn't bother me at all. I have the backlighting always ON and don't use the sound. I don't have the battery popping out problem. Maybe it's because I bought it new. I've read conflicting reviews, 5 stars and 1 star, from people who say they are electrical engineers. Some say this meter is good and others say it's junk. It's hard to judge who is right. This is my first EMF meter. For my purposes, it works well. Using my "new eyes" analogy previously mentioned, I just need to detect an unseen light is there and that it's strong enough to hurt me. I don't need to know the exact details of the light. I need to know how I can weaken that light and be able to detect it's now weaker and at safe levels.

I love this device. After reading information from the international meeting about Cellular radiation concerns at the Israel Institute for Advanced Studies and Dr. Devra Davis on breast cancer, and being a physician myself, I wanted to test my home and my habits. The device is easy to use— just put in the enclosed battery and turn it on. I found much to my surprise that my seat at the kitchen table was a hot spot for intermittent RF probably from my geothermal heating system just below the floor. It was very helpful to put the meter on my chest and watch the effect of simply moving my cell phone an arms distance away. Dittos for getting my husband to stand back 10 feet from the big OLED TV. ( Standing within two feet he was exposed to bursts of RF 5-6 times the federal maximum recommended exposure level. Now, sadly, this does not measure 5G but hopefully that technology will be available in the future. And when it is I will make sure to get this brand. The Company is awesome. I had my meter fall off my coffee table with a stack of papers and it hit just perfectly to maximize impact. It damaged the RF part of the device while the rest (electric and magnetic fields) were ok. I was sad but contacted the company. They promptly responded and coordinated return. They fixed it at no cost and turned around the repair in under a week. Best customer service you could want. You will a learn a lot by having this device in your life. We are being bathed in cellular radiation and as Dr Davis said, the same technique for denial of cigarette smoking dangers are being used to deny cellular phone radiation danger. I live daily with Ionizing radiation as an Orthopaedic Surgeon, and I’m not unreasonably paranoid, just reasonably cautious. I am a member of the first generation of humans to be bathed in radio waves and now we are going to be subjected to MICROWAVES. It is a great experiment on human physiology. This device helps you monitor and mitigate your exposure.

Works as promised. Have used for several electrical fixes.

As an EE and having worked in a building where faulty electrical wiring resulted in wildly wobbly CRT displays, I've always had an interest in perceiving or detecting these everyday but invisible fields. The Trifield 100XE has been on my Wishlist for quite some time, but never quite reached the threshold of an order. Recently I noticed this new model TF2, and the superior specifications and display readability compelled an order. The meter arrived with battery already installed. The new case design is smart, modern and high quality. With the backlight on, the display is remarkably clear and informative. The analog display (the bars) uses a logarithmic scale to convey maximum information at a glance. The digital read-out updates several times a second, frequently enough to track a changing value but still allowing the value to be read. The peak value digital read-out significantly boosts the meter usefulness by capturing short signals that otherwise would not be reflected in the analog or digital read-out. The hold time of the peak read-out is just right. While initially checking out the meter around the house, I was amazed that holding the meter in front of a loudspeaker produced a field strength display synchronous with the music playing (should not have been amazing, of course). The TF2's extended RF frequency range allowed me to check my 5 GHz WiFi access points and note the intermittent pattern of actual transmissions. While checking my microwave, I did notice a scale gap since the leakage safety limit at two inches is 5 mw/cm^2 vs. the meter's scale limit of 1000 mw/m^2. The centimeters vs. meters difference results in factor of 10,000, so the safety limit converted to the meter's scale units is 50,000 mw/m^2, far in excess of the meter's measuring range. So it's necessary to take readings at a greater distance. Using a wooden yardstick to position the meter 36 inches away from the microwave reduces the field strength to approximately 1/320 of the value at two inches. When I performed this measurement I found that my 10-year old microwave significantly exceeds the current safety limit, so I'll need to follow up on that. *** Follow up - March 11, 2018 *** It occured to me that a microwave oven is not a point source of radiation hence the inverse square law is not accurate at room-sized distances. Then I located a paper on the NIH website entitled "Exposure assessment of microwave ovens and impact on total exposure in WLANs" which includes an adhoc formula mapping the field strength vs. distance. The so-called "path loss exponent" is a parameter in this formula. It would be 2 for the perfect inverse square law. However, for distances less than one metre, and with 275ml water in the microwave oven, the adhoc value (as listed in the paper) is only 1.20. This change in exponent means that the RF value measured at 36 inches away from the microwave reduces the field strength to just 1/32 of the value at two inches. With this change of calculation my 10-year old microwave oven is just fine for RF leakage.

This thing comes loaded with the batteries. All you do is pull the tab. Don’t have to read 1 million directions. Just wanted to learn about things in my house that might be admitting dangerous things from my health! I hate putting things together and reading directions this I literally pulled the tab and went to work

Great meter and fast shipping! Thanks

I bought this RF meter after watching some Youtube videos about RF radiation. I decided to get this meter and experiment for myself to see what causes and what mitigates radiation. Once I received it, I compared all different devices throughout my house and was amazed at what I found. Here are some of my discoveries: - Wifi signals are usually around 50 when measured at the source. - Cellular data signals are routinely maxing out the meter at over 1,000,000, so stick to wifi as much as you can! - Cellular data signals are stronger than our microwave oven turned on high! Not only does this remind me to use my data less and keep the phone away from my head, but it also puts my mind at ease about using my microwave oven! You could hold your head up against the microwave with it turned all day long, and be no worse off than anyone using their phone all day. - I put several extra layers of drywall on my office wall, and it blocks about 100% of RF radiation. - Smart meters are REALLY bad for you. They are maxing out the meter from several feet away! - A cheap metal waste basket can be used as a Faraday cage for all of your electronic devices, and will block about 90-95% of radiation from going in or out, even from the smart meter that is on the other side of this wall. - Signal strength decreases dramatically with distance, about a factor of 10 every 2-3 inches at first. So just putting your phone on speaker and holding it two feet away from your head while you talk will decrease the radiation you are receiving to basically zero. - There are REALLY high signals at every street corner. I can't tell exactly how strong because I think the signal is coming from high up somewhere, but assuming it's 10 or 20 feet up, and based on the signals decreasing by the inverse square of the distance, it would have to be millions or billions of times stronger than the smart meter. I guess this is either cellular stations or smart meter stations. All four houses around our street corner have had people die of cancer in them just since I moved onto this block. I think just the peace of mind that this device will give you makes it worth buying. For example, I will no longer have to second-guess my decision to use a microwave oven when other friends or neighbors are too paranoid to use them. And now I don't have to worry about giving myself brain cancer every night while I sleep with my phone under my pillow; instead I just turn off cellular data, and set my phone on my night-stand a few feet from my head when I go to sleep. I can still reach it whenever I want, but I know it's having practically no impact on my health now.

Initial experimenting shows it works well right out of the box, and battery was already installed, even. All seems to work great!

Das Gerät ist im Vergleich zu den anderen Angeboten etwas teurer, aber auch deutlich besser. Die Messwerte sind plausibel und reproduzierbar. Das Gerät hat sehr schnell reagierende Sensoren und erfasst gepulste HF Strahlung wirklich gut. Perfekt zum Aufspüren von elektromagnetischen Strahlungen. Wer einen wirklich funktionierenden Detektor sucht, wird hier fündig. Die Grenzwerte sollte man bei der KI erfragen - da gibt es unterschiedliche Auffassungen. Nebenbei eine tolle analog anmutende Bedienung (ich liebe richtige Bedienknöpfe).

Thanks for great trade

Given our dependency on technology (and because I'm a crunchy granola hippy), I thought it'd be interesting to see the EMF levels in our house and the surrounding neighbourhood to ensure we are not being zapped. Things to keep in mind: we live in India. Our house is a farm house in a semi-rural area, but is quickly urbanising. Our home is constructed of thick cement that honestly rivals a WWII bunker. It's my understanding people should not be exposed to more than 60 V/m (the standard ELEC setting) and 1 mW/m squared (the RF setting). What we discovered is this (and what the pictures hopefully illustrate): --My cell phone, which is an Apple 8 and generally connects to either the WiFi or LTE when using cell service, had a very high reading on RF, and it would frequently max out the reader. Most of the time it got 6-11 and up to 20 mw/m when the call was connected, and 2-3 when not connected. It was at .2-something when in airplane mode. Best to keep calls to a minimum, hold the phone away when connecting, either keep the call short or hold it on speaker phone when talking, and then put it in another room when done. RF is negligible when the phone is far away, so that's good. --Electrical outlets are really high at 400 V/m when switched on, to the point that it's advisable to switch off all outlets when not in use or when not needed. This is especially true if you sleep next to power outlets due to the positioning of the bed. --Though this is the case, the V/m drops considerably when one backs up even just a few feet. So, even just moving furniture a few feet away from outlets can help significantly. --Laptops should never be used when plugged in, because the EMFs were off the charts--it often topped out the reader went to insane levels of 900-1,000! I had no idea how dangerously high my computer got when connected to a power source, and now I will absolutely not use my computer on anything other than battery. In fact, I will be willing to replace the battery in my machine when it gets depleted, rather than use it plugged in. I wish I knew this earlier, as my previous laptop HAD to run from a power source on account of the battery being exhausted. I had used it this way for years, yikes! When on battery, no EMF levels were detected. --Our router showed 262 V/m. It too dropped when one moved away, to the point that where I sit the next room over, I have a reading of 0 V/m. --My husband's work station has a number of computer screens, a wireless mouse, wireless keyboard, tons of wires, and he loves his gadgets. He sits next to the router. With all these things, his station is 260 V/m at chair level, worse when he moves closer to the offenders. I'm trying to convince him to rejig his office. --The large yard enclosing our house (and most houses, I imagine) reads 0 V/m. --When leaving our house to walk along the road strung with electrical poles (as we do in the evenings), the reading is 60 at my head height and 70 at my husband's. When I hold the reader as high as it can go, the reading as 120+ V/m. The reading is 120+ at head height when walking past the transformers and junction boxes. I'll be rethinking the walks up and down the road, for sure. --On the second floor, the reading is 0: this is good, considering that the poles get more intense with height. Thankfully the house seems far enough away to put the influence of these poles to null. I can edit this review and include more info when we visit our flat in the heart of the city, to see if that makes a difference. Hopefully this helps either persuade someone to buy the product or be mindful of the things I learned. So yeah, great product, definitely worth the spend for the information it provided. Very easy to use.

creo q funciona bien pero aun no he tenido el suficiente tiempo para valorar una experiencia
