As a gaussmeter, electric field meter and radio field strength meter in a single unit, the Trifield Meter delivers superior detection when you need to be able to detect the true strength of an electromagnetic field. Able to identify AC electric fields, AC magnetic fields, and radio/microwave fields, the Trifield Meter helps you prevent electromagnetic pollution by identifying the root cause. We know that electromagnetic fields are everywhere – but the Trifield EMF Measurement Meter can show you just how large your level of exposure is.

Readings are quick and accurate and can be taken regardless of meter orientation. Use it to measure artificial magnetic fields rapidly from sources ranging from overhead power lines and internal wiring to leaky microwaves and cell phone towers.

The best way to prevent EMF overload and excessive exposure is to limit your contact with these fields. Use the Trifield EMF Measurement Meter to find EMF hot spots in your home or office and arrange your environment accordingly. Remember – the effects of EMF are still being studied, but many report a reduction in exposure can improve one’s sense of well-being, energy levels, and focus.

Product Specifications:
