The Concrete Water Impermeability Tester Three Points apparatus is supplied complete with graduated burettes fixed on the front panel. Concrete Water Impermeability Tester Three Points apparatus is used to determine the depth of penetration of the water into the concrete (impermeability) under known time and pressure. The water penetrated is measured by breaking the specimen, or by reading the water permeated through the graduated burette. The unit accepts concrete cubic, cylindrical or prismatic specimens having max. dimensions of 200x200x200 mm. A manometer checks constantly the applied water pressure. A known water pressure is applied on the specimens surface for a known time, as requested by Standard, using a suitable air compressor having at least 5 bar pressure.
