Static Testing Equipment
Name：LFY-406 Fabric Surface Specific Resistance Tester
Details
The main purposeThis instrument can be used to measure the surface specific resistance (surface resistivity) of various fabrics, carpets, films and other insulating materials. The surface specific resistance can indirectly reflect the length of the static leakage time on the surface of the test material, thereby reflecting the static electricity of the test material performance.
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 apply a DC voltage of (100±5) V 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.
Technical index
1. Adopting a highly integrated 3 1/2-digit digital display.
2. Range: 1×105Ω ～9.999×1014Ω
3. The test voltage is: DC 100V.
4. Working environment temperature: (23±1)℃, humidity: (25±5)%RH
5. The zero drift of the instrument is less than ±5% between 1-8 hours at a stable working voltage and no signal input
6. The basic error of the instrument to the standard resistance measurement: ≤±10%
