Protective clothing Electrostatic Charge Attenuation Tester
Electrostatic Charge Attenuation Tester
Product Description
The Electrostatic Charge Attenuation Tester uses the induction effect of step voltage to charge the test specimen, and measure the half-life and shielding coefficient of the specimen in a non-contact state.
Electrostatic Charge Attenuation Tester Standards:
T/CNTAC62-2020 Protective clothing - Electrostatic performance test - charge decay method
EN 1149-3 Protective clothing-Electrostatic properties-Part 3: Test methods for measurement of charge decay-test method 2
