Testex TN150 산/알칼리 침투성 미터

Standards: GB/T 24540

Acid / Alkali Penetration Tester, to determine the penetration resistance to acid and alkali for protective clothing by using conductive method. The time of penetration is reported.

Using conductance method and automatic timing device test fabric pH class penetration time of chemical protective clothing. The specimen is placed between the upper and lower plates; conductive wire are connected with plate and also contacted with the specimen surface, when the liquid penetration occurs the circuit conduction, timing stopped.
