From the manufacturer’s website:

Speedy 2000 Moisture Testers are widely accepted for rapid, accurate, and reliable moisture tests on materials such as sand, aggregates, ores, coal, soils, ceramics, abrasives, and other powders. The Speedy moisture testers are portable, easy to use, and do not require a power supply.

Samples can be tested on-site in minutes, eliminating the risk of moisture loss during transport. Place a weighed sample in the tester with a measured quantity of MAA-44 Calcium Carbide Reagent (due to shipping restrictions is sold separately) and seal with the cap. Upon agitation, free moisture in the test sample reacts with calcium carbonate to form acetylene gas. The pressure gauge reads directly in percent moisture by weight within 1–3 minutes. Moisture ranges can be doubled for all models by using 1/2 specimen weight and multiplying gauge reading by two.

Testers are available in four different models based on sample material, percent moisture range, and desired gauge accuracy. Each tester comes as a kit that contains testing components needed for moisture testing. All units have a tough, die-cast polished aluminum pressure chamber with an integral dial gauge. Each Speedy 2000 kit includes an electronic balance, reagent measuring scoop, brush, cleaning cloth, and instructions in a heavy-duty, waterproof case.
