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.
