LFY-406H Anti-static clothing resistance tester

Main purpose

This instrument can be used to measure the point-to-point resistance, point-to-ground resistance, and internal resistance of cuff and wristband grounding devices of various anti-static clothing, groundable static clothing, and other insulating materials, thus reflecting the electrostatic performance of the tested materials.

Instrument characteristics

This instrument test device primarily consists of a flat-plate electrode setup and a high resistance meter. The fundamental principle involves applying direct current voltage of varying levels to the sample. The minute current flowing through the sample is sampled and amplified by a standard resistor, and then read from the high resistance meter. The digital display directly shows the resistance value, offering high precision, rapid display, good stability, and convenient reading.
