Best available technique for your specific purposes
easy to use online – tensiometers measure dynamic surface tension, fully automated foam testing system performs test of foam-ability and foam decay, process control instrumentation monitors your cleaning processes.

Easy and safe to handle bubble pressure tensiometers for most convenient use in R&D applications as well for Quality Control purposes and monitoring of processes.

SITA DynoTester

Tensiometer SITA DynoTester
– small and precise hand-held tensiometer for quick Quality Control or in field users.

  • 3 adjustable bubble lifetimes between 15ms – 15s – suitable for broad range of applications
  • One keystroke gives you the surface tension value of your sample at the correct bubble lifetime
  • Easy offline monitoring of wetting agent or surfactant concentration


SITA pro line t15

NEW! – Tensiometer SITA pro line t15
– compact and flexible tensiometer for multipurpose use in R&D, Quality Control and Process Monitoring.

  • Bubble lifetime range of 15ms – 15s – suitable for broad range of applications
  • 3 special measurement modes for the typical tasks in R&D, QC and Process monitoring
  • Optional external output of surface tension by electrical current signal for process integration
  • Easiest to use multipurpose bubble pressure tensiometer


SITA pro line f10

Tensiometer SITA pro line f10
– reliable tensiometer, for use at the production line in discontinuous or continuous measurement tasks.

  • Bubble lifetime 40ms – 800ms covers most typical wetting agent or surfactant concentrations in cleaning or electroplating processes
  • Endless continuous measurements with optional flow through system possible
  • Automatic measurement of dynamic surface tension curves through the whole bubble lifetime range


SITA science line t60

Tensiometer SITA science line t60
– small yet precise tensiometer for use in and outside of laboratories especially for R&D purposes

  • Bubble lifetime 30ms – 60s covers applications with focus on very dynamic to semi-static surface tension
  • Continuous measurement of adjustable period without a drift of bubble lifetime
  • Automatic measurement of dynamic surface tension curves through the whole bubble lifetime range
  • Many parameters can be set by user


All measured values can be compared independently from the used SITA tensiometer because of the common measurement technology and the automatic control of bubble lifetime.
Laboratory guidelines can so be used for in field quality or process control.

The Main Fields of Application for the SITA Foam Tester R-2000

The SITA Foam Tester R-2000 is the first foam testing instrument that can test surface active liquids in foam using a newly developed method. It is therefore exceptionally suitable for the body care and detergent industries. The fully automated testing procedure, as well as the highly reproducible test results, offer an optimum foundation for use in Research and Development, such as in Quality Control.
