     Speedy Moisture Meter 
    Using a speedy moisture meter, the moisture content
    of soils, sand and other fine-grained material can be obtained quickly with
    reasonable accuracy. The test technique is based on the fact that water will
    react with calcium carbide to form acetylene gas and the quantity of gas
    formed is directly proportional to the water present, leaving a surplus of
    the chemical used in the test. The quantity of acetylene gas produced is
    indicated on a built-in pressure gauge, which is calibrated in percentage of
    moisture on wet weight basis.
