MA-20A

This popular method is widely accepted for rapid, accurate, and reliable moisture tests on sand, aggregates, ores, coal, soils, ceramics, abrasives, and other materials. Units are portable, easy to use and do not require a power supply. Samples can be tested on-site, eliminating risk of moisture loss during transport.

A pre-weighed sample is placed in the tester, along with a measured quantity of calcium carbide reagent. When the chamber is sealed and agitated, free moisture in the test sample reacts with the reagent to produce acetylene gas. Pressure gauge reads directly in percent moisture by weight in one to three minutes. All units have a rugged, die-cast aluminum body (pressure chamber) with integral dial pressure gauge. Accessories are included as noted, and are also available as replacements, as noted below. Replacement accessories are interchangeable between models. The 0-20% Aqua-Check Replacement Pressure Gauge is compatible with Speedy-brand Moisture Testers, MA-26, MA-21A and MA-25.

MA-26 Gilson Aqua-Check™ is an economical choice, meeting all requirements for use with soil, sand, aggregates, coal and ores. Aluminum body is 14x5.5in (356x140mm) LxDia and finished in tough, wear-resistant coating. Aqua-Check kits include electronic digital balance, two 1.25in (32mm) diameter steel balls for pulverizing samples, reagent measuring scoop, a 1lb (0.45kg) can of reagent, brush, and instructions in a heavy-duty, waterproof plastic case.

Speedy Moisture Testers are available in four different models, based on particle size, moisture range, and gauge divisions desired. Standard-sized MA-20A and MA-21A, are 12x4in (305x102mm) LxDia, and used for clays, fine powders, grain and sand. Large MA-25 and MA-25C are 14x5.5in (356x140mm) LxDia, and handle soils, aggregates, coal and ores. MA-25 and MA-25C include two steel balls to pulverize samples. Kits also include electronic balance, reagent measuring scoop, a 1lb (0.45kg) can of reagent, brush, and instructions in a heavy-duty, plastic case.

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.
