VICKSBERG Penetrometer (Proving Ring Type)
Model No. STE0019
It is a portable unit used for measuring the moisture content of a number of materials including soils, aggregates, dust and powders (and liquids). Moisture measurements are done by mixing a weighed sample of the material with a calcium carbide reagent in the sealed pressure vessel. The reagent reacts chemically with water in the sample, producing acetylene gas that elevates the pressure within the vessel. The pressure increase in the vessel is proportional to the amount of water in the sample, the moisture content readings can be seen directly from the calibrated pressure gauge.
