Speedy Moisture Tester is a portable system for measuring the moisture content of a wide range of materials including soils, aggregates, dust and powders (and liquids). The system consists of a low pressure vessel fi tted with a pressure gauge and an electronic scale and test accessories. Moisture measurements are made 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 in turn increases the pressure within the vessel. The pressure increase in the vessel is proportional to the amount of water in the sample, the moisture content can be read directly from the calibrated pressure gauge. The tester is supplied complete with heavy-duty plastic carrying case, electronic balance, beaker, cleaning cloth, cap, washer, scoop, steel pulverizing balls and cleaning brushes. Meets ASTM D4944 and AASHTO T217. Shipping Wt. 13 lbs. (5.9kg). Accuracy: Within 0.5% on most materials. Test Speed: 45 sec. to 3 min., depending on material. Gauge: Calibrated from 0-20% moisture based on wet weight. Balance: Electronic; 0-7 oz (0-200g) range; battery operated

Speedy moisture tester quickly and accurately detects moisture content of soil, sand, clay, aggregate and other granular materials in powder, mixture and paste form under field conditions. Capacity: 20 gr. It is supplied as a set with Precision Balance, measuring spoon and cup, 1 box of calcium carbide reactant, cleaning brush, 2 balls and carrying case.
