Safety Instructions
Review and understand all of the operating and safety instructions before using this unit.
WARNING!!
The calcium carbide reagent used with this test must be handled with great care. When exposed to
water, calcium carbide produces highly flammable or explosive acetylene gas.
•
Users must understand and follow local regulations and calcium carbide Material Safety Data Sheet guidelines and
procedures regarding transportation, storage, handling and disposal.
•
Testing must not be performed in confined spaces or in the vicinity of an open flame, lighted cigarettes, embers or
any potential source of ignition.
•
When releasing the gas from the apparatus, make sure to direct it away from your face and body.
•
DO NOT store, dispose of, or place the calcium carbide reagent where it may come into contact with water, because
it can produce explosive acetylene gas.
•
Any application not specifically covered in this manual will be considered improper use and will void the warranty.
•
Testing excessively wet material, adding water to the testing chamber, or improper use of the equipment could
cause pressures to exceed the safe level for the apparatus.
•
Long sleeves, gloves and eye protections should be worn at all times when performing the test.

•
(2) 1.25in (32mm) Steel Pulverizing Balls
•
Long-handled Reagent Scoop
•
Large, coarse clean-out Brush
•
Small, fine-bristle brush
•
Sample cup
•

Introduction
The Aqua-Check Moisture Tester is designed to measure the water content of soils, aggregates, and other
non-reactive materials. The Aqua-Check consists of an aluminum sample chamber vessel with integral pressure
gauge, electronic balance for sample weighing, two steel pulverizing balls, and assorted brushes and containers
as required for proper completion of the test.
Pulverized calcium carbide is used as a reagent, and reacts when combined with water in the sample material to
form acetylene gas. The most accurate results are obtained when pressure gauge readings are correlated with
data from over-dry methods.
