Detects: Magnetic fields, electric fields, and RF (20 MHz–6 GHz; includes most 5G but not experimental millimeter waves). Does not detect radioactivity.
Displays EMF fluctuations fully: bars update instantly for fast digital signals, while RF and number averages refresh 4 times per second. Other meters over-average or filter field peaks, giving slower, less complete readings.
Features: 3-axis magnetic, single-axis electric (with standard or weighted frequency responses), and single-axis RF readings (unweighted). Weighted readings emphasize effects on the human body.
Measures: 4G and 5G cell phones, cell towers, WiFi routers, Bluetooth, AC Powerlines, and Smart Meters. The TF2 responds to RF very fast compared to other meters.
Includes: Trifield TF2 meter, 9V battery, Quick-start Card, Detailed Instruction Manual, and soft-shell, zipper carry case.
Manufactured and Serviced in USA by AlphaLab, Inc. with a 1-Year Manufacturer Limited Warranty. Free, unlimited consulting to help solve your EMF issues included.

AWESOME MACHINE
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!

Safety in the home. What an excellent tool.
A wonderful tool for my Health Box. It is amazing the lack of knowledge I had of my home and it’s hidden dangers. This tool has opened my eyes. Making changes for my family’s health future. Thank you for such an easy to use tool.
Great quality!! –
Gives a strong accurate reading for the value
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.

How to choose an EMF meter?…..it’s confusing!
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!

Masterpiece from AlphaLab
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 is a real quality meter
There are a lot of meters on the market. This has been the standard for a long time. Having a meter really helps me plan my car routes to avoid the towers. Worth it as RF is cumulative. I also used it to check for dirty electricity in my home. I realized I had a lamp that wan’t grounded and spewing dirty electricity and much more.

Worth buying if you are worried about EMF levels in your area
Used this to get some EMF readings before buying land near power lines. Was really helpful in gaining some ease of mind with our purchase. I felt the readings were accurate and aligned with levels you would expect. Works as intended and will give you a good baseline of EMF levels in a variety of areas

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.

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.
