COULOSCOPE® CMS2 STEP Electrochemical Thickness Measuring Instruments

Measurement of coating thicknesses and electrochemical potentials according to the coulometric method

The CMS2 STEP features the additional STEP Test (Simultaneous Thickness and Electrochemical Potential determination) function. It is used for standardized STEP Test measurements of individual coating thicknesses and differences in potential (according to ASTM B764-94 and DIN 50022) in the quality control of multiplex nickel coating systems. The coating thickness measurement is carried out according to the coulometric method, while the potential profile is captured using a silver reference electrode coated with AgCl.
