Moisture Content determination is an important part of testing in the field of agriculture, civil engineering, pharmaceutical industry etc. The standard oven drying method is a time consuming and expensive method which can not be used for routine testing where a large number of tests are to be carried out during the progress of work as a control on raw material etc. For routine & quick testing There are two types of instruments with us, i.e. Rapid Moisture Meters and Torsion Balance Moisture Meters. The results of Rapid Moisture Meter depend upon the chemical reaction between the free moisture content present in a material and a chemical powder, resulting in the formation of a gas in a air tight vessel. The pressure formed inside the vessel is recorded on a pressure gauge which is directly calibrated in terms of moisture content. Torsion Balance Moisture Meter is a heating type instrument in which a small sample, approx. 6gm., is used. The wet weighing, drying, dry weighing, and moisture content readings are obtained in the same unit. It is an accurate apparatus and gives results comparable with the oven drying method. Rapid Moisture Meter 0-25% The moisture meter is most suitable for fine grained sandy soils and such other materials. The instrument is specially useful in the field since it is fully self contained in a light weight wooden carrying case and no power supply is required. The equipment utilizes the chemical reaction of calcium carbide powder with the free moisture present in the specimen in a sealed air-tight vessel. The resultant gas pressure is recorded on a pressure gauge which is calibrated to read directly moisture percentage. Accuracy of the instrument is 0.25%. The equipment consists of a pressure vessel fitted with a pressure gauge and sealing clamp along with sealing cap, a counter poised balance to weigh 6 g of sample, a scoop for measuring calcium carbide powder, a bottle of calcium carbide powder, cleaning brush and steel ball charge. Complete in a wooden carrying case Rapid Moisture Meter 0-50% Same as above, but the instrument is fitted with a pressure gauge calibrated for 0-50% moisture content.
