Trifield™ Meter Model 100XE

Manufactured in the USA by AlphaLab, Inc.

Trifield  Meter measures all three types of electromagnetic field: AC magnetic field, AC electric field, and radio (including microwaves). The magnetic and electric detectors are 3-axis, making the meter easier to use than comparable 1-axis meter (en français).

*The Radio/Microwave section of this meter reads most modern radio sources (50 MHz - 3 GHz). For lower radio frequencies and/or stronger radio sources (such as measuring the field near a transmitter), see the Trifield BroadBand 100XE Meter.

SKU: TF100XE $145 ($150 for phoned in orders)

Frequency Options:

60 Hz: Calibrated for North American power frequency (and certain other regions).
50 Hz: Calibrated for European power frequency (and certain other regions).
Flat: Specialized meter with flat frequency response at 50 and 60 Hz. Not sensitive above 2000 Hz.
ES: Extended Sensitivity to frequencies down to 5 Hz (electric and magnetic). Not recommended for general electromagnetic testing because it takes longer to stabilize after being moved.

Available Options:
AC Power: $50, External Coil 10X Magnification: $65, LED Illuminated Display (for darker environments): $50, Output Jack: $20
Sound: $50, Uni-Directional Switch $35, Hard Carrying Case: $18

Available Data Acquisition Option:
Data Logging USB Stick: $140 Logs data from the meter. The stick must be connected to a computer to operate. If the output jack option is selected, the output of the TriField Meter is proportional to the needle deflection and is not linear. The output jack is included in the price of the option.

Product Description:

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.
