LFY-406Z Material Vertical Resistance Tester
The main purpose
This instrument can be used to measure the surface specific resistance and vertical resistance of various fabrics, films and other insulating materials. The size of the resistance can indirectly reflect the length of the static leakage time on the surface of the test material, thereby reflecting the static 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 different gears of DC voltage 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.
