FST-100TPH Foam Stability Tester is a national standard brewery foam tester. According to the standards of NIBEM institute, FST-100TPH Foam Stability Tester measures the foam collapse time over a distance of 30mm. This measuring method is objective and believable, since it can well avoid the effect of flow. Besides, the effect of temperature, atmospheric pressure and humidity can also be calibrated.

Measuring principles:
FST-100TPH evaluates the foam stability through measuring the disappearing speed of brewery foam. Foam is an unstable mixture of air and liquid. The reasons why the foams disappear are as below:
1) Small foams consolidate to larger foams.
2) Foams are not in equilibrium (the effect of surface tension).
3) Consumption, coming from the damage to foams by foam liquid flow.
4) Gas diffusion.
