The Trifield ® Meter is a gaussmeter, electric field meter, radio field strength meter in a single unit. When measuring electromagnetic fields (EMFs), the primary concern is usually magnetic fields, which can be tricky to measure. If a less sophisticated 1-axis gaussmeter is used, a reading of zero could result even where the field is strong. A 1-axis meter must be oriented correctly to measure the field (which is a vector). The 3-axis Trifield Meter solves that problem by measuring the true strength of the field regardless of which way it is oriented. Therefore, the Trifield Meter can be scanned rapidly across an area without having to stop at each point to search for the orientation that gives a maximum reading. Another section of the meter detects AC electric fields, which can exist independently of AC magnetic field. The third section detects radio/microwave, such as from a leaky microwave oven.

제품특징

Detects the three types of electromagnetic pollution: AC magnetic fields, AC electric fields, and radio/microwaves.

AC magnetic and electric fields are 3-axis, allowing quick accurate readings regardless of meter orientation.

Two magnetic ranges cover 0.2-100 milligauss.

This is sufficiently sensitive to detect the background field almost anywhere (except far from civilization), while measuring up to very strong AC fields.

Electric range covers 5-1000 V/m (or .5-100 kV/m with original version of the Trifield Meter)

Radio/microwave covers 10 to 1000 microwatts/square cm which includes the maximum permissible public exposure levels in all countries.

Operates about 40 hours on replaceable standard 9V battery, has a low battery indicator.

Analog (needle-type) display has very fast response time compared to digital. (However, AlphaLab also manufactures digital meters.)
