The LCM Liquid Content Module for the DFA100 measures the moisture of foams with respect to time on different foam height levels. The results are obtained by detecting the foam’s conductivity as a proven method. They provide you with knowledge about a foam’s stability and help you optimize products where moisture plays a key role, such as washing foams.
