Gauss Meters and Probes

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 measurement. Its light weight and small size allows the operator to rapidly and conveniently measure magnetic fields with the same accuracy as many laboratory instruments, but with the added convenience of hand–held portability. Three full–scale bipolar ranges of ±100.0 gauss, ±1.000 kilogauss, and ±10.00 kilogauss with 100% overrange and resolution of 0.1% provide DC and AC field readings from ±0.1 gauss to ±19.99 kilogauss (using 1x probe). True RMS measurements can be made from 10 Hz to 20 kHz. Readings are displayed on a 3-1/2 digit LCD display and are also available via the analog output connector. The analog output has a range of ±200 mV where 100 mV represents the full–scale range of the instrument. In addition, a wide selection of pre–calibrated transverse and axial Hall probes are available to meet most applications. This includes probes that can extend the measuring range of the MG–4D up to 150 kilogauss. Standard features include battery operation, padded vinyl carrying case, and a 6 foot probe extension cable.
