The Gilson Aqua-Check Moisture Tester is an economical choice for rapid, accurate, and reliable moisture tests than the Speedy® Moisture Testers 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. The Aqua-Check, recently evaluated by the Florida DOT has been verified to meet the FM5-507 DOT requirements. The evaluation showed that it provided reasonable comparisons to actual moisture content determinations by oven and microwave drying methods. Samples can be quickly tested on-site, eliminating risk of moisture loss during transport.

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 Gilson Aqua-Check Moisture Tester has a rugged, die-cast aluminum body with a tough, wearresistant coating and includes a 0—20% pressure gauge, with certificate of calibration. Recalibration of existing Aqua-Check gauges is available.

Also included; electronic digital balance, two 1.25in (32mm) dia. steel pulverizing balls, reagent measuring scoop, brush, and instructions in a heavy-duty, waterproof plastic case. 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.
