Demonstrating Why Calcium Chloride Tests Don’t Measure Vapor Emissions

Calcium chloride testing is often misunderstood, especially when it comes to what it actually measures. In this video, Jason Spangler, Vice President of Sales at Wagner Meters, breaks down exactly why calcium chloride testing does not passively measure vapor emissions from a concrete slab. Jason walks through how the test works, explains the limitations of its design, and demonstrates these principles by performing a calcium chloride test in real time. By clearly showing what the test is, and is not, measuring, this video helps flooring professionals better understand moisture testing results and make more informed decisions before installation.
