LFY-259E Chemical Protective Suit Liquid Tightness Tester

Main purpose

This is used to test the liquid chemical penetration resistance of chemical protective suits, including: testing the penetration performance of spray liquid-tight chemical protective suits, splash liquid-tight chemical protective suits, and limited splash liquid-tight chemical protective suits.
