Bubble Pressure Tensiometer – BPT Mobile BPT Mobile – Krüss

Introducing the BPT Mobile Bubble Pressure Tensiometer

Experience immediate surfactant concentration assessment in your baths with the BPT Mobile Bubble Pressure Tensiometer by Krüss. Designed for rapid and precise surface tension (SFT) measurements, this device empowers quality inspectors with instant ad-hoc evaluations, ensuring your bath’s compliance and optimal surfactant levels at all times.

Applications Across Industries

This versatile instrument serves a wide range of applications, from determining detergent concentrations in cleaning baths before coating or bonding, monitoring wetting agent levels in electroplating baths, to ensuring the right surfactant levels in baths for acid mist mitigation in electrolyte baths. Its efficacy extends to the quality checks of various coating baths, including those for solar cells, and the monitoring of etching baths for circuit boards.

Dynamic Measurement for Accurate Results

Utilizing dynamic surface tension measurement through the Laplace pressure of a gas bubble at a capillary in a liquid, the BPT Mobile offers insights into surfactant concentration, dynamic surface tension at a defined surface age, and temperature of the tested liquid. Its technology is tailored for use cases such as the optimal application of surfactants, wetting, adhesion and cleaning for coatings, and interfacial chemical investigations for offset printing and metal plating.

Designed for Ease of Use and Reliability

The BPT Mobile operates independently of a computer or power grid, boasting a user-friendly touch display for intuitive operation. Its sophisticated data management system simplifies evaluation processes, supported by disposable capillaries for hassle-free maintenance. Quality control has never been more streamlined, making the BPT Mobile an indispensable tool for your quality assurance tasks.
