Speedy Rapid Moisture Meter
For quick determination of moisture content of materials in powder form viz. Soil, sand, coal, pottery slip, cement etc. Calcium carbide when comes in contact with moisture acetylene gas in generate. This principle is used in rapid moisture meter. A weighted quantity of sample is mixed with fixed quantity of calcium carbide reagent and the whole mixture is thoroughly shaken in a vessel to which a pressure gauge is fixed. The acetylene gas produced developes pressure and pressure gauge is calibrated to read percentage moisture. The instrument indicates moisture on wet/weight basis easily convertible to dry weight basis.
