SITA Dynotester Tensiometer

New SITA Dynotester Plus

Portable Bubble Pressure Tensiometer

APPLICATION SCOPES:

The DynoTester couples accuracy and speed for dynamic surface tension measurements at many different bubble lifetimes. It can be operated handheld or as a tabletop instrument for your convenience. Software is additionally available for auto-data collection.  Dynamic surface tension measurement is available for any liquid used in all fields including: electroplating, environmental, biological, personal care, household cleaning, semi-conductor etching/photoresist liquids and etc.  It has time-saving and accurate operation in addition to its portable or stationary function for maximum efficiency and efficacy.  It can work with a special process software module, SITA ProcessLog, to make it even more efficient.
