MG-5DAR / DP

Portable Hall Effect Gaussmeters

The MG-5 Series are general purpose portable Hall effect gaussmeters designed to measure both DC and AC (RMS) magnetic fields.

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 ±100 milligauss to ±19.99 kilogauss with true RMS readings from 3 Hz to 20 kHz; readings are displayed on a 3½ digit ±0.1% bipolar LCD meter.

The MG-5D 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 every application, including probes which will extend the measuring range of this instrument to 150 kilogauss.

The MG-5 Series operates either from AC or from sealed lead acid batteries. During AC operation, the batteries receive a trickle charge which keeps them fresh until the instrument is required for portable use. Freshly charged batteries will continuously operate this instrument for approximately 10 hours.

In addition, an analog output is also provided for external monitoring.

MG-5DAR In the auto-range mode, the MG-5DAR will automatically switch to the appropriate full-scale range to accurately display the measured field and provide optimum field measurement resolution.

A reading of more than ±1999 counts will automatically switch this unit to a higher range and a reading of less than ±100 counts will automatically switch this unit to a lower range. The decimal point indicates the operating scale.

MG-5DP In the Peak Mode, the MG-5DP will sense and display the most recent peak magnetic field level from DC to 20 kHz.

This instrument can be set to either detect the peak value when the field is bipolar (varying from positive to negative) or it can be set to exclusively detect either the positive peak or the negative peak of a varying field. Because of the digital circuit design, there is no decay in the peak field reading.
