Friction-charged charge tester

(Faraday cylinder method)

[Scope of application]: Fabric friction and charged charge test instrument

To test the static properties after fabric friction with charge under laboratory conditions, but also to test the anti-static properties of anti-static clothing and anti-static fabrics, as well as the review of labor safety certification and production license, suitable for class A and class B anti-static work clothes.

[Relevant standards]: FZ / T01060 GB12059 GB / T12703 et al
