  • LZ-642 is a portable 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-642 can display N/S, with the high resolution of 0.1G, it can be used for detecting the residual magnetic of machining, the remanence of work-piece 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.

    Probe Features

    The standard configuration of LZ-642 is transverse probe. There are also axial probe for customer selection.
    The probe is composed of tip, body, hand shank, cable, connector, sheath and calibration code.
    In the tip of probe, there is a hall sensor, which is very fragile. The thickness of tip is 1.2mm and the width is 3.5mm.
    The body of probe connect with tip and hand shank and extend tip to the suitable operation position.
    Hand shank is the only part which operator can hold during the measurement. In some special applications, operator can use some fixed device to hold the hand shank, so that the tip of probe keep stable during the measurement.
    The cable connects the electric from tip to connector. The length of it is 1.5 m. The connector is 5 core plug, and connect with the socket at the tip of LZ-642.
    Sheath is used to protect the tip and body shank of probe.
    All the probes have a separate calibration code. The calibration code is located near the probe connector. The calibration code can be input to the LZ-642 by keyboard.
