Applications: This series of instruments is a direct-reading digital high-resistivity tester, suitable for measuring ultra-high insulation resistance, ordinary wires and cables, cross-linked polyethylene cables, and the resistivity of insulating materials. It is also suitable for weak current measurement, electronic component measurement, photoelectric measurement, bioelectricity measurement, and atomic energy research. With an optional electrode box, it can measure the surface resistance and volume resistivity of insulating materials.
