High precision destructive S2000 measuring system for detecting moisture in concrete, sand cement and other bricky material. The water present in the sample reacts (chemically) with calcium carbide. This produces pressure in the vessel, which is proportional to the residual moisture content. Insensitive to external influences, always displays the right value. Complete set in carrying case with balance, pressure cylinder, calcium carbide and cleaning tools.
