How to test the surface resistance of electrostatic bags?
Surface resistance tester is to measure the antistatic products surface resistance, so as to detect anti-static products anti-static ability. ASTM D-257 Standard Test method according to the instrument, the two test by testing at the bottom of the parallel copper electrode quick test resistance surface, only placed on the need to measure the object surface and press the red button, 10 lights on the instrument 10 -10. Or LED insulation lights will be lit according to numerical test. The indicated value of the illuminated LED lamp is the surface resistance of the object under test.
Test instrument:The surface resistance tester with three in one function is the best instrument, giant Wang Wuxi three in one type surface resistance tester plastic material limited company on the sale of products can be measured surface resistance, conductive performance and test of products, but also test whether insulation products.
Surface resistance of an object: 12 ohms with a resistance greater than 10; an insulator.10 times greater than 6, less than 10 square ohms, 11 ohms for anti-static body.3 times 10, less than 10, the 5 ohm is the conductor.
