aqua check moisture tester

MA-26 Gilson Aqua-Check Moisture Tester Gilson Aqua-Check is an economical choice for rapid, accurate, and reliable moisture tests on sand, aggregates, ores, coal, soils, ceramics, abrasives, and other materials with particle size up to 20mm. Portable units are easy to use, and meet ASTM, AASHTO 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. MA-26 Aqua-Check 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 as MAA-53, inquire. 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. Approximate pressure chamber dimensions: 14x5.5in ( 356x140mm) , LxDia. MAA-45 Aqua-Check 0— 20% Pressure Gauge, replacement gauge includes a certificate of calibration, and is also compatible with Speedy-brand MA-21A and MA-25 Moisture Testers. All accessories are compatible with both Aqua-Check and Speedy-brand Moisture Testers. 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. For areas where shipping of calcium carbide is cost prohibitive, the Gilson Aqua-Check is available in a complete kit with no reagent as MA-26X. Est. Ship Wt.: 15lb ( 7kg) .
