Description and Specification for Lab Tenders
Speedy Moisture Meter (D2 Large).
It is a portable unit used for measuring the moisture content of a
number of materials including soils, aggregates, dust and powders (and
liquids). Moisture measurements are done by mixing a weighed sample of
the material with a calcium carbide reagent in the sealed pressure
vessel. The reagent reacts chemically with water in the sample,
producing acetylene gas that elevates the pressure within the vessel.
