Rapid Moisture Meter is a portable apparatus designed for quick determination of moisture content in soil, sand, cement, coal and other powder / granular materials in a laboratory or site environment. The method is based on the chemical reaction of free water in the sample with calcium carbide (or other absorbent material) inside a sealed vessel. As the reaction occurs, acetylene (or gas) is generated, increasing internal pressure, which is measured via a calibrated gauge and converted into % moisture content.
The unit typically is supplied as a complete test kit: a pressure vessel with sealing clamp, rubber sealing gasket, pressure gauge, a small counter-poised balance for weighing the sample, steel mixing balls, scoop for reagent, cleaning brush, and reagent bottle all packed in a polished wooden carrying case for portability.
Rapid Moisture Meter is useful in any scenario where rapid approximate measurement of moisture content is needed rather than waiting for long ovendrying tests. Typical applications include:
Geotechnical / soil testing: Determining moisture content of soil samples for compaction, foundation design, stability assessment.
Construction materials: Checking moisture in sand, cement, aggregates before use (because moisture content affects mix design, strength, curing).
Foundry / casting operations: For sand and green sand where moisture content impacts moulding and casting performance.
Production / QC environments: Where quick pass/fail moisture checks are required in a workflow, for materials like powders, granular components.
Field testing: Because the apparatus is portable, it can be used on-site to validate materials prior to use without needing full lab oven facility.
General lab use: As a faster alternative to conventional ovendry drying for preliminary moisture measurement.
