MG-4D

Hand-Held Gaussmeter

The MG-4D is a fully portable hand-held Hall effect gaussmeter designed as a true self-contained instrument for DC and AC (RMS) magnetic field measurements.

Light and small in size, the MG-4D provides the operator with both the convenience of hand-held portability and the accuracy associated with laboratory instruments.

Three full-scale bipolar ranges of ±100 Gauss, ±1 kilogauss and ±10 kilogauss with 100% over-range and resolution of 0.05% provides DC and AC field readings from ±0.1 Gauss to ±19.99 kilogauss (1X probe) with true RMS readings from 10 Hz to 20 kHz; readings are displayed on a 3½ digit ±0.1% bipolar LCD meter.

The MG-4D is a Hall effect instrument and uses a Hall Probe to couple with and measure the magnetic field. A wide selection of precalibrated transverse and axial Hall probes is available to meet most applications. The measuring range of this instrument can be extended to 150 kilogauss with select probes.

Standard features include batteries, carrying case, and a 6' extension probe cable.

An optional battery eliminator allows AC operation. Alkaline batteries can also be replaced with "AA" rechargeable batteries.
