Measuring foam formation and decay speed for quality control – reliably and reproducibly
Foam is a welcome companion to many products, but almost as often it is a nuisance that must to be avoided. Either way, for quality control of your products and processes, it is necessary to exactly determine the foaming behavior of the liquids and foam-inhibiting additives involved. The easy-to-use Foam Tester – FT carries out this task reliably and in an exactly repeatable manner. Using accurately controlled gas flow and precise electronic foam height measurement, the Foam Tester gives you significant results for the foaming capacity of your liquid and the decay speed of the resulting foam.
