LFY-259E chemical protective clothing liquid tightness tester
The main purpose
It is used to test the penetration performance of chemical protective clothing against liquid chemicals, including: testing the penetration performance of spray liquid-tight chemical protective clothing, the penetration performance of splashing liquid-tight chemical protective clothing and the penetration performance of limited splash chemical protective clothing .
