DRK453 protective clothing acid and alkali resistance test system-protective clothing resistance to hydrostatic pressure tester
1. Main Purpose
This equipment is developed in accordance with the national standard GB 24540-2009 “Protective Clothing for Acid and Alkaline Chemicals”. It is mainly used to test the hydrostatic pressure resistance of fabrics for acid and alkali chemical protective clothing. It is expressed by the hydrostatic pressure value of the fabric. The resistance of the agent through the fabric.

DRK453 protective clothing anti-acid and alkali test system-protective clothing penetration time tester
1. Main purpose
According to the national standard GB 24540-2009 “Protective clothing acid-base chemical protective clothing”, this equipment uses the conductivity method and automatic timing device to test the penetration time of the fabric acid-base chemical protective clothing. The sample is placed between the upper and lower boards. , The conductive wire is connected with the upper board and is in contact with the upper surface of the sample at the same time. When the penetration phenomenon occurs, the circuit is turned on, an electrical signal is sent out, and the time is recorded. The penetration time of the sample.
