Protective clothing against acid and alkali tester is developed according to latest GB24540-2009 《protective clothing-acid and alkali chemical protective clothing》. Sorted by the inspection items, this device can be divided to static acid pressure tester, acid and alkali repellant tester, and acid penetration time tester. It is mainly used to test the against acid and alkali performance of the protective clothing. Widely used in protective clothing manufacturing enterprise and every quality testing bureau Protective clothing chemical resistance tester is mainly used to test the breathable type protective clothing anti acid and alkali performance. The testing liquid flow on the surface of the specimen, check whether the liquid retention or penetration, and calculate the anti acid and alkali index.
Anwendung
