TriField TF2 EMF Meter

If you need to know your exposure to different EMFs, the TriField TF2 EMF Meter can be used as an AC gaussmeter, an AC electric field meter, and also a radio frequency (cellular phones, WiFi, etc.) meter. The TriField Meter combines all the features needed for fast, accurate measurements of electromagnetic fields (EMF). Along with standard AC measurement modes, it has a special frequency weighted mode that will properly scale the magnetic and electric measurements to indicate the full magnitude of currents produced by each type of field inside the human body.

More info

The TriField TF2 EMF Meter has several functions: it is an AC gaussmeter, AC electric field meter, and radio power density meter in a single unit, which combines all the features needed for fast, accurate measurements of electromagnetic fields (EMF). If you want to know how much electromagnetic frequency you are surrounded by, this meter will help you find out the amount of EMF you are exposed to.

It detects three types of EMF pollution: AC magnetic, AC electric, and RF/microwave. It has a special frequency weighting mode for measuring EMF in the human body. The ‘AC Magnetic Mode’ covers 40 Hz – 100 kHz, and the measurements are 3-axis, allowing for quick readings, regardless of meter orientation.
The ‘AC Magnetic Mode’ covers 40 Hz – 100 kHz, the ‘AC Electric Mode’ covers 40 Hz – 100 kHz, and the RF Mode covers 20 MHz – 6 GHz with a range of 0.001 – 19.999 milliwatts per square meter (mW/m2).

The Trifield meter is easy to use, with a large LCD that shows accurate readings clearly. It can be used in low-light environments as it comes with an adjustable backlight, and its audio indicator helps in spotting EMF sources easily. It can operate for more than 20 hours with the backlight off, and up to 12 hours with the backlight on. It comes with a 9V alkaline battery that includes a low battery indicator.

*Note. The TF2 is poor at detecting ambient radio frequency, only providing a measurement close to the source of emission. We recommend the Acousticom 2, although this dips at the 5.6GHz frequency. The most reliable high-frequency detector is the Safe & Sound Pro II.

It can detect:

  • Mobile phone and cell tower RF radiation
  • Smart meter RF radiation
  • Household appliances with EMF emission
  • Wi-Fi router and Bluetooth RF radiation
  • Overhead AC power line and transformer EMF emissions
  • EMF emission inside aircraft and motor vehicles
  • Microwave oven leak
  • Location and EMF of wiring in walls
  • EMF from plumbing pipes
