Digital Gaussmeter, Dgm-204

We offer Digital Gaussmeter, DGM-204 operates on the principle of Hall Effect in Semiconductors. A semiconductor carrying current develops an electromotive force, when placed in a magnetic field, in a direction perpendicular to the direction of both electric current and magnetic field. The magnitude of this e.m.f. is proportional to the field intensity if the current is kept constant. This e.m.f. is called the Hall Voltage. The small Hall Voltage is amplified through a high stability amplifier so that a millivoltmeter connected at the output of the amplifier can be calibrated directly in magnetic field unit (gauss).

Applications
Wide application in industry where accurate measurements of magnetic field is required.
Measurement of steady magnetic field e.g. in loud speakers, dynamo, moving coil instruments etc.

Useful in laboratory experiment involving measurement of magnetic field.
With easy interchangebility of Hall Probe, same gaussmeter can be used with both transverse and axial probe.
