Kruss - Bubble Pressure Tensiometer - BP50

By checking the surfactant content of a cleaning or galvanic bath directly on site, with the utmost precision and in just a few seconds, our Bubble Pressure Tensiometer – BP50 provides optimum support for your process control. The BP50 measures the dynamic surface tension, which, particularly in the case of high surfactant content, reacts sensitively to changes in concentration. Our BP50 has been specially developed for use in quality assurance. During the flexible high-speed test, the software automatically signals whether the measured value lies within a limiting range that you have set or whether the surfactant content needs to be adjusted.
