The ST – 250 Speedy Moisture Tester quickly and accurately measures the moisture content in virtually any powder, mixes, and pastes of soil, sand, clay, or other granular material. In a speedy Moisture Tester, the moisture in the test specimen reacts with calcium carbide reagent to form acetylene gas in the pressure chamber. The amount of gas formed, and the pressure gauge on the tester is calibrated to directly read the percentage of moisture contained in the specimen. The Speedy Moisture Tester permits accurate testing of specimens in the field, with typical test times as short as a few minutes. Each Speedy Moisture Tester is supplied complete with balance, measuring spoon, cleaning cloth and brushes, calcium carbide reagent and polished oak carrying case.
