    Model LZ-680

     
  Model LZ-680 Gaussmeter / Teslameter  
     
Brief Introduction

  LZ-680 is a desktop gaussmeter which is suitable for both AC and DC magnetic field measurement. It is used for measuring the surface magnetic field of permanent magnet and the working magnetic field of DC motor, magnetic separator and permanent de-ironing separator.

  LZ-680 has the function of displaying N/S, which is convenient for checking the polarity. With the high resolution of 0.1G, 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. The function of AC measurement can be used for detecting the AC space magnetic field distribution.

  LZ-680 can be connected to computer by the USB interface, and quickly form the magnetic field monitoring and measurement system by the software.

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