The Speedy is widely accepted for rapid, accurate, and reliable moisture tests on
all kinds of materials–sand, aggregates, ores, coal, soils, ceramics, abrasives, and
other powders. 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.
Selection of four available models is based on particle size, percent moisture
range, and gauge accuracy desired. Standard Models MA-20A and MA-21A
are used for sand, grains, clays and fine powders. Large MA-25 and MA-25C
handle soils, aggregates, coal and ores. Moisture range may be doubled by
using 1/2 specimen weight and multiplying gauge reading by two.
All units have tough, die-cast polished aluminum body (pressure chamber)
with integral dial. Place weighed sample in the tester with measured quantity
of calcium carbide reagent and seal with cap. Upon agitation, free moisture
in test sample reacts with calcium carbonate to form acetylene gas. Pressure
gauge reads directly in percent moisture by weight within 1—3 minutes.
Each Speedy 2000 Kit includes an electronic digital balance, reagent measuring scoop,
one can of reagent, brush, cleaning cloth, and instructions in a heavy-duty, waterproof
plastic case. MA-25 and MA-25C include two steel balls to pulverize samples. 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.
Speedy Moisture Testers MA-20A and MA-21A are 12x4in (305x102mm), LxDia.
Model MA-25 and MA-25C are 14x 5.5in (356x140mm), LxDia. Est. Ship Wt.: 15lb (7kg).
