MeasureDGM-HH-01 operates on the principle of Hall Effect in semiconductors. A semiconductor carrying current develops an electromotive force when placed in a magnetic field. The direction of this emf is perpendicular to both the electric current and the magnetic field directions. Also this emf, called hall voltage, is proportional to the intensity of the magnetic field if the current is kept constant. The small Hall Voltage is amplified in the unit by highly stable amplifiers so that its value could be read on an LCD DVM. The display of course is calibrated in Gauss. The complete unit operates from a single 12V SLA battery. A lamp on the front plate indicates when recharging is needed. A dedicated charger comes with the unit.  

Applications

Extremely convenient magnetic field measurement in industrial environment. Can operate on inbuilt SLA battery for long durations without recharging.

Measurement of steady magnetic field in dynamos, loudspeakers as well as magnetic field in many fixed equipments in workshops, laboratories etc..
