Analyze surface roughness and surfactants with these devices
Krüss
Two highlights being exhibited at this company’s stand are a surface-roughness analyzer and a bubble-pressure tensiometer. The Surface Roughness Analyzer (SRA) supports the optimization of materials or production process that require a surface that must be very smooth, show a certain texture or a required degree of roughness. The SRA gives users a 3-D image of a sample’s surface and provides data that exactly describe its topography, quickly, without contact and with an extremely high resolution. Also on display is the Bubble Pressure Tensiometer (BPT) Mobile (photo) — a hand-held device for quality control of cleaning and coating baths. Users can simply immerse, click, and read out the surfactant content of a parts-cleaning bath within seconds. The device is based on surface tension measurements, and an ad hoc evaluation of the data informs the quality control inspector if the bath is okay. Moreover, for proactive adjustment of the bath, the BPT Mobile shows how the surfactant content decreases over time due to removed parts, for example. Hall 7.1 Stand D60 — Krüss GmbH, Hamburg, Germany
