A Gauss Meter can measure the direction and the intensity of small (relatively) magnetic fields. For larger magnetic fields, a Tesla Meter, is used, which is similar, but it measures in larger Tesla units. A Gauss Meter comprises a gauss probe/sensor, the meter and a cable connecting both. The Gauss Meter works on the basis of the Hall effect discovered in 1879 by Edwin Hall. Please contact us for more details.
