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

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.

I still have to learn how to use it. It was quite the little investment. I love it though, made in the United States runs on a single 9 V. Battery comes with a nice case and directions, works perfectly. I just need to update my knowledge base to understand it all. very happy with my purchase. I would not even consider purchasing a lesser brand or quality!!! Thank You TriField for making such a quality instrument!

It is easy to use and clear results.

Although the TriField has 2 annoying design flaws (you can’t adjust the volume and the volume and adjustable light buttons are inside the battery compartment) it’s still a safe and excellent choice. It’s easy to operate, it measures 3 of the 4 most important frequencies (hard to find in one meter!), it’s light weight, comparatively small and it’s the most affordable one with these features. Im extremely sensitive to ElectroMagnetic Frequencies/Radiation so, having a meter is such an Important first step in feeling better AND being proactive with your health. I take it everywhere with me because EMR affects my sleep, mood, energy and health. There’s a sense of comfort having the meter in hand. Customer service 10 star ⭐️ Customer SERVICE: 10 ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️ I worked with Kristina at AlphaLab. and she was great. Foremost, she acknowledged a couple of design flaws with out getting defensive. She said AlphaLab is making note of customer feedback to make improvements for future models. This is professional and logical; why waste time defending things if everybody knows here’s a problem with them. In addition to being honest, they followed through on everything they said...and quickly. She stayed on top of things and was never out of touch more than 2 days. She took the initiative when it came to a technical issue and sent out a replacement meter before I asked. Then, even after the replacement worked perfectly, they still offered a full refund because the design inconveniences! That’s impressive and definitely uncommon. I think this shows integrity. The communication was easy and honest. Offering me the refund reassured me so much, it helped me decide I wanted to keep the meter . I wish more companies and service reps were like them....outstanding!

This works great! It is small enough to fit in a purse or tool box but the quality is still strong to capture an active reading. I bought this as I was looking at several houses that were near power lines and wanted to get a reading from the backyards. This worked well and was a good value for the money. The battery life was also longer than I expected.

I'm a novice but this appears to be a quality product.

Everyone should have this meter because it helps you find the electrical hotspots in your living area. The older Trifield was not so valuable but this newer one has audio and a digital readout, very efficient at helping assess problem areas. We had a bed with huge ELF readings right at the pillows. Bed got moved to a safer wall and we sleep well now. Had a desk where everyone got headaches and the Trifield showed it was blazing with bad energy so we moved the desk away from the hot wall. We asked our electrician why we have some walls that are so high in electromagnetic energy-- showing up to 360 volts on the electric dial-- and he does not know. He checked the outlets and they were balanced correctly but there is something wrong with our old wiring that defies conventional knowledge. If you can't afford to tear out walls and put your wiring in protective conduit, like the building biologists now recommend, then at least use this meter to help you locate your hot spots and reconfigure your furniture accordingly. Low frequency exposure over time badly drains the body's energy. Don't sleep in it above all. Get your bed to a very low electromagnetic area for a better life. And while you're at it, turn off your blasted carcinogenic Wi-Fi. That's loaded with both low frequencies and microwaves-- a ticket to aging and disease. We don't know if the microwave portion of this new meter is responsive to Wi-Fi because we learned long ago to keep a microwave-free house.

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.
