Bubble Pressure Tensiometer
BPT Mobile
Mobile quality control for cleaning and coating baths
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
-
Monitoring the content of acid mist mitigating agents in electrolyte 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
Includes all software it needs
The BPT Mobile works independently from a computer or the power grid and is simply recharged via USB. Up to 20 million results find room in a clear folder structure. The display shows all necessary graphical representations and makes evaluation in other software obsolete – yet possible thanks to a fast data export to Excel.
Don’t bother with subsequent cleaning
We have replaced costly, high-maintenance permanent capillaries that are customary for the bubble pressure technique with disposable ones. Inserting and ejecting them is a matter of seconds, cleaning them a matter of the past. The temperature sensor, which is read for each measured value, can also be quickly removed when testing soiling or corrosive solutions
