SITA t100 The Research-Grade Tensiometer

SITA t100,  a “NEW” SITA Research-Grade Bubble Pressure Tensiometer

APPLICATION SCOPES:

A bench top or portable tensiometer for R&D continuous monitoring, as well as dynamic surface tension auto-scan from low to long bubble lifetime.  Measuring dynamic surface tension measurement for any liquid used in all fields such as electroplating, environmental, biological, personal care, household cleaning, semi-conductor etching/photoresist liquids and etc.  It has an option to work with the software module, SITA LabSolution, to make it even more efficient.

METHODS:

Maximum Bubble Pressure Method.

FEATURES:

User-friendly features;

• Fast set-up
• Compact and robust
• Quick measurements
• Easy to operate
• Interchangeable capillaries
• Long term measurement up to several days
• Interface for process control is possible
• Automated calibration
• Touch key menu access for selection of operation mode, calibration and clean mode
• Calibration against water

Allows measurements either at:

• Constant surface age (bubble lifetime)
• Automatically increasing surface age (bubble lifetime)
• Measurement independent of immersion depth
• Ease of switching among samples
• No density value of sample to be entered prior to measurement
