Moisture Tester 0-20%, 20g Sample
The Moisture Tester is an economical choice for rapid, accurate, and reliable moisture tests than the Speedy Moisture Tester and meets all requirements for use with sand, aggregates, ores, coal, soils, ceramics, abrasives, and other materials with particle size up to 20mm. Portable units are easy to use, and meet AASHTO T217, ASTM D 4944, and Florida DOT requirements.
In use, a pre-weighed 20g sample is placed in the test chamber, along with a measured quantity of calcium carbide reagent. When the chamber is sealed and agitated for one to three minutes, free moisture in the test sample reacts with the reagent to produce acetylene gas. The integral pressure gauge registers 0—20% moisture by weight in 0.2% graduations. Moisture range can be doubled by halving the pre-weighed sample weight.
The Moisture Tester has a rugged, die-cast aluminum body with a tough, wear resistant coating and includes a 0—20% pressure gauge, with certificate of calibration.
Calcium Carbide Reagent in 10lb cans is purchased separately.
Approximate pressure chamber dimensions: 14x5.5in (356x140mm), LxDia.
Reagent must be purchased separately. Due to shipping restrictions, additional reagent is sold in 10lb (4.5kg) cans. Material from these larger cans can be used to replenish smaller containers for field use.
