Bubble Pressure Tensiometer – BPT Mobile

Mobile quality control for cleaning and coating baths

Industrial quality assurance is about reliability, speed, and ease of use. When it comes to regular checks of the cleaner or wetting agent content in a bath, our Bubble Pressure Tensiometer – BPT Mobile is prepared for these demands.


  • Cleaning as a preparation step before coating or bonding
  • Electroplating
  • Coating of solar cells
  • Etching, e.g. for circuit boards

Measuring methods and options

  • Bubble Pressure method: SFT is measured using the internal pressure of a bubble at an immersed capillary
  • Monitoring at a single surface age with evaluation based on predefined limits
  • Continuous measurement of SFT while changing the concentration
  • Determination of the SFT dependent on surface age between 10 and 30,000 ms
  • Temperature measurement and documentation
