SITA pro line t15+

The compact all-round tensiometer measures the dynamic surface tension in three different modes: Single, Auto and Online. This gives it all the functions for a wide range of measuring tasks such as the analysis of wetting behaviour, concentration control or determination of the influence of temperature.
