DGSI. Durham Geo Slope Indicator

Moisture Testing Kits

Determine the moisture content as percent water of most soils in about 3 minutes. The measured sample is placed in the pressure chamber with calcium carbide reagent. The water in the soil and the reagent react to produce acetylene gas. The gauge reads the percent water content from 0-20% based on weight with an accuracy of 0.5%.

The Moisture Testing Kits comprise of a pressure chamber with a dial gauge, scale, cleaning brushes, cloth and measuring scoop packed in a sturdy case.

It is available in two sizes, 6 gram for fine grained materials and powders and 20 gram for sand, aggregates and lumpy materials. Reagent and calibration kit are available separately.

The original S-142 Speedy Moisture testing Kit is comprised of a sturdy, waterproof carrying case containing a large, highly polished pressure chamber for 20 g samples, a 200 g electronic balance, and other related items.

The new 20 gram Aqua-Check, S-142A, is similar but comes with a tough, wear-resistant coating instead of a polished canister and is economically priced.

DGSI maintains a full line of repair parts, accessories and service for the Moisture Testing Kits.
