LFY-406A material resistivity tester
The LFY-406A material volume resistivity and surface resistivity tester can be used to measure the surface resistivity (surface resistivity) of various fabrics, carpets, films and other insulating materials. The surface resistivity can indirectly reflect the surface static electricity of the test material The length of the leakage time reflects the electrostatic charging performance of the test material.
The main purpose
This instrument can be used to measure the surface specific resistance (surface resistivity) and volume specific resistance (volume resistivity) of various fabrics, clothing and other insulating materials, so as to reflect the electrostatic charge performance of the test material.
Instrument characteristics
This instrument uses the three-electrode method to test the sample. The test device mainly consists 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.
