General Test & Measuring Instruments

Digital Gauss Meter, Model: DGM- 204

  • Wide Range (0.1 G to 40 K.Gauss) 
  • Excellent Linearity
  • Excellenct Stability
  • Built-in Computer Interface


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. This small Hall Voltage is amplified through a high stability amplifier so that a milli voltmeter connected at the output of the amplifier can be calibrated directly in magnetic field unit (Gauss)


  • Current from photo multiplier tubes, photometers etc.
  • 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 interchangeability of Hall Probe, same Gauss meter can be used with both transverse and axial probe.
