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. 2. Main Technical Indicators
