Product Introduction
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

Probe Features
LZ-680 equips transverse hall probe.
Probe constitutes of tip, body, handle, cable, connector, protective tube and calibration number.
There is hall sensor in the tip of probe, it is frangible and located 3mm away from the tip. The size of tip after enclosure is 1.2mm in thickness and 5m in width.
Probe body as the connector of handle and tip, it can extend the tip to the position for easy operation.
Handle is the only part which operator can handle during the operation, in some certain applications, operators can use fixed system to fix the handle to guarantee the stability of tip.
The cable connects tip electric to connector, the length of it is 2m. The connector is DB15-core plug, which can connect to the probe socket in the rear panel LZ-680.

LZ-680 can also equip with axial probe, there are two kinds of axial probes: I and II. For I , the hall sensor lies in the body of the probe and 2mm from the tip, it only suitable for measuring uniform magnetic field, and not fit for surface magnetic field, but is has the AC measurement board band of 5kHz. For II , the hall sensor is in the same level with the tip, it can measure both uniform magnetic field and surface magnetic field, but the AC measurement board band is restrict to under 100Hz.
We do not contain axial probe as standard equipment.
