had al een simpele emf meter ,maar deze trifield biedt loepzuivere readings van electrische - vuile electrische ,magnetische en rf ( o.a. wifi en 5 g ) velden , top product voor relatief lage prijs ten opzichte van presicie metingen , makkelijk bedien-, en afleesbaarheid , uitschakelbare zoemer en display licht .

It spot any kind of radiations. The best on the market. Cost a bit more but measure also RF radiations which others do not. Screen with retro light for measures in the dark. Possibility to put sounds on.

L'avantage étant qu'il dispose de plusieurs plages de fréquences contrairement à beaucoup d'appareil.Large spectre de fréquences, visualisation en temps réel à l'aide d'une jauge, bruitage augmentant en intensité lorsque la puissance du signal augmente.J'en suis très satisfait.

Easy to use and works consistently. I've been able to pinpoint hot spots for electrical activity as well as RF / Wireless which has allowed me to change my environment in ways that reduce my exposure to these things. Who would have thought that my alarm clock gave off so much static electricity, which was even still measurable on my pillow - disappearred when the alarm clock was unplugged. This device showed me the electrical reading coming off of my powered recliner which prompted me to hook that up to a power bar which I switch off once I get my comfortable position. Greatest concentration of electricity pretty much exactly where you sit. Not good for my boys! A very useful tool indeed. Highly recommend.

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.

Ich habe mir das TriField EMF-Messgerät TF2 zugelegt, um die elektromagnetische Strahlung in meiner Wohnung zu überprüfen, und es hat mich wirklich überzeugt! Es ist einfach zu bedienen und zeigt mir präzise Messwerte für alle drei Arten von EMF: elektrische Felder, hochfrequente Felder (RF) und magnetische Felder. Die Handhabung ist unkompliziert, und das Gerät liefert schnell zuverlässige Ergebnisse. Es gibt mir ein besseres Gefühl für die Strahlung in meiner Umgebung und hilft mir, meine Wohnung zu optimieren. Für alle, die sich über EMF-Strahlung informieren wollen, kann ich dieses Messgerät nur empfehlen!

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.
