The TriField TF2 EMF Pollution Meter is a versatile handheld device designed to detect and measure three types of electromagnetic fields: magnetic fields, electric fields, and radio frequency (RF) radiation. Covering RF from 20 MHz to 6 GHz, it includes most 5G bands (excluding experimental millimeter waves), making it a future-ready tool for assessing modern wireless environments. Whether you are concerned about cell towers, WiFi routers, smart meters, or power lines, this meter provides comprehensive readings in one compact unit.
What sets the TF2 apart from other EMF meters is its instant-response bar display. While many meters average out or filter field peaks, the TF2 updates its bar graph instantly for fast digital signals and refreshes RF and numeric averages four times per second. This ensures you capture the true fluctuations of pulsed signals from devices like 4G and 5G phones, Bluetooth, and WiFi. The meter also offers weighted electric field readings that emphasize frequencies that affect the human body, giving health-conscious users more relevant data.
Build quality is solid, with a durable plastic housing and a clear, easy-to-read LCD screen. The controls are intuitive: a single switch selects the measurement mode (magnetic, electric, or RF), and the bar graph and numerical display work together to show both instantaneous and averaged values. The included soft-shell zipper case protects the meter during transport, and the detailed manual helps beginners interpret readings accurately.
One limitation is that the electric and RF sensors are single-axis, meaning you may need to rotate the meter to find the strongest signal direction. Additionally, the meter does not log data or connect to a computer, so it is best for spot-checking rather than long-term monitoring. However, for most home and office assessments, these are minor trade-offs given the device's accuracy and speed.
Overall, the TriField TF2 is an excellent choice for homeowners, building biologists, and anyone serious about understanding their EMF exposure. With U.S.-based manufacturing, a one-year warranty, and free unlimited consulting from AlphaLab, it offers reliable performance and peace of mind.

Buying Guide for 2026
Field Types Measured: Magnetic, Electric, and RF
Most EMF reader detect three main field types: magnetic fields (MF) from power lines and appliances, electric fields (EF) from wiring and ungrounded devices, and radio frequency (RF) from wireless signals. Basic models like the COLORTREE Handheld EMF Meter only measure magnetic fields, while mid-range units such as the ERICKHILL RT-100 add electric field detection. For full coverage, look for a 3-in-1 meter like the TriField TF2 or the GQ EMF-390, which measure all three. If you need to check both low-frequency sources and modern 5G signals, the TF2 and GQ EMF-390 are the top picks for comprehensive field detection.
Frequency Range Covered
The frequency range determines what signals a meter can detect. For magnetic and electric fields, most meters cover 40 Hz to 100 kHz, which includes household power (60 Hz) and common appliances. For RF, a wider range is better. The GQ EMF-390 covers RF up to 10 GHz, making it suitable for 5G networks, while the TriField TF2 covers 20 MHz to 6 GHz (most 5G but not millimeter wave). The ERICKHILL RT-100S and POROMETISTO ET01Pro cover up to 8 GHz. If you need to check the latest 5G frequencies, the GQ EMF-390 wins on bandwidth.
Single-Axis vs Tri-Axis Sensors
Magnetic fields can be measured with a single-axis sensor (requires orienting the meter in three directions) or a tri-axis sensor (reads all axes at once). For convenience, tri-axis meters like the TriField TF2 and the RDINSCOS RD670 give you a total reading without moving the device. Single-axis meters such as the ERICKHILL RT-100 are accurate but require more care to position. For quick, repeatable measurements, the TriField TF2 is the best choice with its 3-axis magnetic sensor.
Readout, Alarms, and Data Logging
A clear display and useful alarms help you interpret readings at a glance. Many meters feature color-coded backlights (green/yellow/red) and adjustable audio alarms. The ERICKHILL RT-100S and the POROMETISTO ET01Pro both use three-color analog displays. For data logging, the GQ EMF-390 includes a built-in data logger and a real-time RF spectrum analyzer. If you want to track readings over time, the GQ EMF-390 is the clear winner.
Stated Accuracy and Calibration
Manufacturers typically specify accuracy as a percentage of the reading plus a floor value. For example, the TriField TF2 states ±20% accuracy for RF readings, while the GQ EMF-390 claims ±1 dB for RF. Lower-cost meters like the TEMIRUP 5-in-1 do not publish accuracy figures. For critical measurements, choose a meter with published specs. The TriField TF2 is manufactured and serviced in the USA with a 1-year warranty, making it the most reliable choice for accuracy and support.
