Method for monitoring surface tension of wash liquor, particularly during operation of dishwasher, involves moistening test block assembly with wash liquor, where hanging drop or falling drop is formed by moistening

摘要

The method involves moistening a test block assembly (15) with a wash liquor (S), where a hanging drop or a falling drop is formed by the moistening depending on the surface tension. The formation of the hanging drop or the falling drop is drawn as monitoring criteria for the surface tension of the wash liquor. An independent claim is included for a monitoring device for surface tension of a wash liquor, particularly for implementing a surface tension monitoring method.
