Calcium Chloride Concrete Moisture & Alkalinity Test Kit This kit includes 3 calcium chloride tests and a pH test kit. The calcium chloride desiccant container has a label that easily allows for the recording of all pertinent facts related to the test. The test container is made from high quality PETG plastic with a preinstalled gasket system. This anhydrous calcium chloride vapor test kit was developed over 40 years ago to quantify the volume of water vapor radiation from a concrete slab surface over time. This test is directly specified by the vast majority of the Floor Covering Industry as the primary measure of moisture acceptability for floor covering installation. Use this test to model the amount of moisture that emits from 1,000 square feet of slab surface in 24 hours. The result is expressed in pounds which is the equivalent weight of water, emitted as vapor, over 1,000 square feet in 24 hours. Use this result to compare to the manufacturer’s specifications for floor covering or coating tolerances. Always reference a copy of the manufacturer’s specifications when reporting results using this test. This test requires the use of a gram-weight scale with a graduation of 1/10th (0.1) gram. The calcium chloride container is weighed before and after exposure to the concrete slab. It is highly recommended that the test be weighed prior to, and directly after exposure using the same scale to ensure uniformity and accuracy of test results. Call for quantity pricing.
