VAT series dial Teslameter is a kind precision instrument applying Hall effect to measuring the magnetic field strength. It can be used to measure the surface magnetic materials, the magnetic field in the gap of magnetic circuit of loudspeaker, the magnetic field produced by electrified coils, and the remanent magneti of metal parts. The value of magnetic field strength is displayed in dials. And N,S pole can be distinguished directly. This teslameter in measuring, easy to operate, light in weight, convenient for carrying, etc. Three kinds of measuring probes,viz.transverse,lonudinal and thin probe head can be provided.Users can choose the probe according to what they need.
