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.
Applications
• Detergent concentration in cleaning baths, e.g. before coating or bonding
• Wetting agent concentration in electroplating baths
• Quality check of other coating baths, e.g. for solar cells
• Monitoring of etching baths, e.g. for circuit boards
Measuring methods
• Dynamic surface tension using the Laplace pressure of a gas bubble at a capillary in a liquid
Measuring results
• Surfactant concentration
• Dynamic surface tension at a defined surface age, as a one-point measurement or time-dependent
• Dynamic surface tension over a surface age range
• Temperature of the tested liquid
