Introduction * This Gaussmeter instrument is a portable, multi-functional magnetic field measuring instrument, equipped with a high sensitivity, low drift Hall sensor, and applied advanced digital signal processing technology * Suitable for measuring the surface magnetic field of permanent magnetic materials, mechanical parts Magnetic, DC constant magnetic field, magnetic separator or iron remover, etc. * It can be used as a basic magnetic parameter measuring instrument for magnetic material manufacturers and application units, machinery manufacturing enterprises, university scientific research units, etc. Functional features * Magnetic field measurement: automatic range switching, * Magnetic field polarity display: directly display the N / S magnetism of the measured magnetic field. * One-key unit switching: The value can be mT (millites), G (gauss), 1 mT = 10 G. * Maximum value retention: It is convenient to record the maximum magnetic field value when the magnetic field changes rapidly. * One-key zeroing function: used to eliminate the influence of zero drift on the measurement before measurement. * Small size, light weight, low power consumption, very suitable for carrying to the scene measurement. * The standard configuration is a radial Hall probe, to adapt to different measurement scenarios.
