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. The TriField EMF Meter Model TF2 is a portable all-in-one device that measures AC magnetic, electric, and radio frequency (RF) fields. Ideal for use in homes, offices, or vehicles, it helps identify high-EMF areas so you can reduce exposure. A special frequency-weighted mode for both magnetic and electric fields reflects how those fields affect the human body. Made in the USA by AlphaLab, Inc.
