Perfect automatic foam stability testing
Foam stability is an important beer quality parameter. Measuring foam stability, however, has been so far either laborious or inaccurate – or both. The demand for an accurate and user-/locationindependent stability measurement device led to the developement of the automatic Steinfurth Foam Stability Tester. |

About 25 years ago it was Vos Instrumenten who developed the VOS 4000 Hazemeter. This apparatus was the widely recognized reference for measuring turbidity in beer. Distributed all over the world, many well-established breweries have been using this VOS 4000 Hazemeter. The |
