The Impermeability Test Sets are used for the determination of the depth of penetration of water to hardened concrete specimens under pressure. 3 or 6 specimen capacity models and with and without quantitative measurement equipment of water penetratoion models are available. The system can test 150 mm and 200 mm cube specimens, Ø100x200 and Ø150x300 mm cylinder specimens. Up to 10 bar of working pressure is generated on the sample with 0.2 bar precision with compressed air applied to the integral water tank and controlled by a pressure regulator with a pressure gauge. The test sets with the quantitative measurement equipment of water penetratoion the penetration of water is measured through the burettes. The system comprises impermeability gaskets for every cell. The measurement apparatus is supplied as standard. The apparatus has to be fitted with a suitable air compressor.
