LZ-680 Gaussmeter/Teslameter
LZ-680 is a desktop AC and DC gaussmeter among the LZ series gaussmeters. It is used for measuring the surface magnetic field of permanent magnets and the working magnetic field of DC motor and magnetic separators.

LZ-680 has the function of displaying N/S, with the high resolution of 0.1 G, it can be used for detecting the residual magnetic of machining, the remanence of workpiece and controlling the magnetic situation of plating materials, also detecting the magnetism of motors. With AC measurement function, it can be applied for detecting AC space magnetic field distribution.

It can be connected to computer by the USB interface, and quickly form the magnetic field monitoring and measurement system by dedicated acquisition software.

LZ-680 equipments with digital hall probe, it records calibration information, temperature compensation and linear correction coefficient. The probe with high interchangeability.
