The main purpose

This instrument can be used to measure the point-to-point resistance of various fabrics, carpets, films and other insulating materials, so as to reflect the electrostatic charge performance of the test materials.

Instrument characteristics

The test device of this instrument is mainly composed of a flat electrode device and a high resistance meter. The basic principle is to add DC voltages of different gears to the sample, and the weak current flowing through the sample is sampled and amplified by a standard resistance, and then read from the high resistance meter. The number directly displays the resistance value, with high accuracy, rapid display, good stability and convenient reading. Point-to-point resistance test of fabric and point-to-point resistance test of anti-static clothing can be performed.
