The Fully Automatic Sealed Concrete Permeability Tester operates by applying controlled water pressure to concrete specimens to evaluate their resistance to water penetration. The specimens are securely sealed in the test chambers using a pneumatic sealing system to help prevent water leakage around the specimen edges.
