Aqua-Check is made in the USA, and an affordable choice for rapid, accurate, and reliable moisture tests on sand, aggregates, ores, coal, soils, and other materials with particle size up to 20mm. Samples can be quickly tested on-site, eliminating risk of moisture loss during transport. Portable units are easy to use, and meet ASTM, AASHTO and Florida DOT requirements. The device was evaluated by the Florida DOT and verified to meet FM5-507 DOT requirements.

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.

Aqua-Check has a rugged, die-cast aluminum body with a tough, wear- resistant coating and includes a 0—20x0.2% pressure gauge, with certificate of calibration. Also included; electronic digital balance, two 1.25in (32mm) dia. steel pulverizing balls, reagent measuring scoop, a 1lb (0.5kg) can of reagent, brush, and instructions in a heavy-duty, waterproof plastic case.
