SURFTENS universal
SURFTENS universal with 1 manual dosing unit and tilting stage
The modification of the wetting ability of technical surfaces by special surface treatments becomes more and more common in industry and research. For process characterization, adjustment of technological parameters and production control it is therefore absolutely necessary, to measure the surface free energy objectively and accurately before and after the modification process.
