Introduction: 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.
Specifications for 25%: The unit consists of a pressure vessel with clamp for sealing cap, rubber sealing gasket, pressure gauge is calibrated in percentage moisture content 0-25% x 1% on the wet weight basis a counter poised balance for weighing sample, a scoop for measuring carbide reagent, a bottle of reagent, one cleaning brush and a set of 4 steel balls for thorough mixing. Complete in highly polished wooden carrying case with handle.
Specification for 50%: Same as above but pressure gauge calibrated 0-50% x 1 %. Spares: Carbide reagent, in bottles of 400 gms each.

As per BS 812; ASTM D4944; AASHTO T217 standards
The waterproof and durable case offers the highest level of protection. A foam insert secures the contents of the kit: electronic balance, beaker, cleaning cloth, cap, washer, scoop, steel pulverizing balls, and cleaning brushes. The electronic balance has an easy-to-read LCD display.With a range from 0 - 7oz (0 - 200g), the balance is simple to use, accurate, and repeatable.

The Speedy moisture tester determines the moisture content of a broad range of materials. A small sample of the material to be tested is weighed on the balance and then placed in the hand held vessel. A measure of calcium carbide reagent is then added and the vessel sealed.The reagent reacts with the free moisture in the sample to produce acetylene gas, resulting in an increase in pressure within the vessel. The % moisture content of the sample is then read directly from the calibrated pressure gauge.
