Many questions about foam, one universal approach: The DFA​100 Dynamic Foam Analyzer measures the foamability of liquids and the stability of quickly decaying or long lasting foam based on reproducible foaming and height detection. With optional modules operating in parallel, it also measures the liquid content or analyzes the foam structure with regard to bubble size and distribution. The DFA100 supports you in optimizing foam-forming products or helps you to avoid unwanted foam formation.
