BPT Mobile – Bubble Pressure Tensiometer

Immerse – click – read: Capture the surfactant concentration of your bath within seconds using surface tension (SFT) with the BPT Mobile Bubble Pressure Tensiometer. The quality inspector using it knows immediately if the bath is okay thanks to an ad-hoc evaluation. Moreover, for proactive adjustment of the bath, the BPT Mobile shows how the surfactant content decreases over time.

  • Detergent concentration in the cleaning tank, e.g. before coating or bonding
  • Concentration of wetting agent in electroplating bath
  • Monitor the acid mist reducer content in the electrolyte solution
  • Check the quality of other coatings, e.g. solar cells
  • Monitoring of corrosive solutions, e.g. for circuit boards
