The MPS Gaussometer is a rugged, hand-held, analog gaussmeter designed specifically to be an effective tool for measuring magnetism in the field. Prior to developing the Gaussometer, MPS engineers had 15 years of experience with several types of analog and digital gaussmeters. They discovered that the meters were either hard to read or large and cumbersome. For example, the display on a digital gaussmeter continuously jumps and changes making it difficult to read. The analog meters, because they are large and cumbersome, are difficult to use in the field. This is why Magnetic Products and Services developed a portable and easy to use analog gaussmeter that has the accuracy of a high-performance laboratory instrument.

Having experienced the rigors of the field, MPS has built the Gaussometer and probes with the highest quality materials to ensure long durability. Past experience with other gaussmeters requiring frequent probe replacement proved to be not only inconvenient, but costly. To reduce unnecessary probe damage, Magnetic Products and Services developed a flexible and resilient DC probe made of fiberglass. This probe, referred to as the DCP/GR DC Hall effect probe, will give you easy access into tight areas that in the past may have been difficult if not impossible to reach.

The MPS Gaussometer is available in AC, DC, and AC/DC models. Model GM-X, for example, includes a AC gauss coil probe for measuring alternating magnetic fields and a DC Hall effect probe for measuring direct magnetic fields.

For the price, the MPS Gaussometer is the lightest, most accurate, and easiest to use gaussmeter available.

Includes:	Operator's manual, Zero gauss chamber, 4 AA batteries, 1 DC Hall effect probe (transverse orientation) 3 foot DC probe extension cable 1 AC coil probe with 3 foot cable (gauss range )
Options:	AC coil probe with 3 foot cable (milligauss range)

DC Measurements:
Step 1	Attach the DC Hall probe (can be used with or without the 3 foot extension cable).
Step 2	To calibrate the meter, use the calibration number printed on the probe. Set the selector switch to the CAL position and adjust the thumbwheel until the analog meter registers the probe calibration number.
Step 3	Zero the GAUSSOMETER by inserting the DC Hall probe into the zero gauss chamber. Set the selector switch to the DC position and adjust the thumbwheel until the meter registers zero.
Step 4	Place the probe at the location to be measured. One of the eight scale LED's will illuminate and the meter will register the magnetic field reading. For example: when the 100 scale LED is lit and the meter is registering -5 on the upper scale, the meter's full scale is from -100 to +100, and the magnetic field reading is -50 gauss.

AC Measurements:
Step1	Attach either a milligauss or gauss range probe and set the selector switch to the AC position.
Step 2	Place the probe at the location to be measured. One of the eight scale LED's will illuminate and the meter will register the magnetic field reading. For example: when using the milligauss probe, if the 30 LED is lit and the meter is registering 1½ on the lower scale, the meter's full scale is from 0 to 30, and the magnetic field reading is 15 milligauss (gauss when using the gauss range probe).

Checking the Batteries:

Set the selector switch to BATT position, and the meter will register the battery voltage.

Probe Options:

The AC coil probes are available in both milligauss and gauss ranges. The DC Hall probes are 8 inches long and are made of a resilient, flexible fiberglass that resists damage even under the roughest of industrial conditions. All probes can be customized upon request.
