SITA t15 Plus Tensiometer

 Try the on-line demo of SITA T15+ .


New portable tensiometer for QC/In-line continuous monitoring, as well as dynamic surface tension auto-scan from low to high bubble lifetime.   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 can work with software module, SITA LabSolution, to make it become a great R&D tool.

Instrument designed to simplify dynamic surface tension measurements. Three modes (single, auto, online) for perfecting quality control, research and development and in-line process monitoring.  On-line controlled software for 24 hour PLC monitoring is an option.


Maximum Bubble Pressure Method.


User-friendly features;

  • Adaptable to measurement tasks
  • Compact and robust
  • Quick and direct start of measurements
  • Easy to operate
  • Interchangeable capillaries
  • Long term measurement up to several days
  • Preset parameters reliably prevents measuring deviations through incorrect use
    automated calibration
  • Touch key menu access for selection of operation mode, calibration and clean mode
  • Calibration against water

Allows measurements either at:

  • True constant surface age regulation (bubble lifetime)
  • Automatically increasing surface age (bubble lifetime) with a time-efficient whole range scan within 5 minutes
  • Measurement independent of immersion depth
  • Ease of switching among samples
  • No density value of sample needed to be entered prior to measurement
