KRUSS Large Surface Analyzer - LSA

The robotic system for very fast wetting analyses of big-sized samples

Fully automatic measurements on many positions of large sample areas: Our Large Surface Analyzer – LSA combines a precise positioning robot with our Mobile Surface Analyzer – MSA for measuring surface free energy within a second. The system is especially suitable for quality control of cleaned, pre-treated or coated large surfaces due to its easy handling and programming as well as high measuring speed.

Measurement of surface free energy within a second

The automatically moved MSA, with its ability to take measurements in less than one second, is the fastest mobile instrument on the market for determining surface free energy with two test liquids. It does this by means of a non-contact pressure dosing system that places two drops on the sample, followed by an automatic image analysis of each drop including contact angle measurement and SFE calculation. With our Large Surface Analyzer – LSA, these features are enhanced using the quick and precise positioning of the instrument between measurements.

Powerful positioning robot in different sizes

The Large Surface Analyzer – LSA has one vertical and two horizontal axes and is designed to handle sample sizes of 495 × 565 mm. A second standard model allows operators to position the instrument as desired on an even larger surface of 2900 × 3150 mm. Upon request, customized systems in other sizes are possible.
