Handheld Gauss Meter is a device which is used to measure units of gauss or tesla. It is basically operated on the principle of Hall Effect in Semiconductors in which semiconductor carrying current produces an electromotive force. If current is constant, its magnitude is proportional to the field intensity. This device is widely used for the measurement of steady magnetic field like loud speaker, dynamos, moving coil instruments and many more items. Widely useful in laboratory experiments, this Handheld Gauss Meter is offered to our customers at very reasonable rates.
DGM-HH-02 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 16x2 LCD. The complete unit operates from a 3200mAH Li-ion battery pack, ensuring 7-8 hrs of continuous operation. Charging cable comes with the unit.
