DFA100FSM - Máy phân tích bọt động

DFA100FSM – Dynamic Foam Analyzer

Time-dependent analysis of bubble size in liquid foams

The FSM Foam Structure Module for the DFA100 captures the bubble size and size distribution of foam using intelligent video image analysis. The results help you to produce foam with the shape you want it to have. They also show the decay of long-lasting foam, long before it actually collapses, thus supporting you in optimizing foam stability.
