Ideal for detecting dirt, oxidation, and corrosion on metal surfaces. Surface cleanliness measuring instrument.
The features of the new model include a compact and highly flexible measurement head, measurement control and data collection via WINDOWS XP, and surface analysis using an XY table (optional). While surface potential measurements alone are not very sensitive to changes in the very top layer of the surface, by applying charge through corona discharge and measuring the surface potential before and after, it is possible to sensitively measure surface cleanliness in relation to the exposure of newly formed metal surfaces, the growth of oxide layers, contamination layers, and adsorption layers.

basic information
The change in surface potential due to the charge imparted to the solid surface by corona discharge is quantitatively evaluated using a Kelvin probe with the vibrating capacitance method to assess the level of contamination on the surface of substrates such as metals. Since the measurement can be completed in a few minutes, it can be used not only for the development of cleaning processes but also for product management and cleaning solution management on production lines.

Company information
By adopting special sputtering and plasma CVD processes, we provide high-quality coatings with excellent adhesion even at low-temperature treatments below 180 degrees, along with high film thickness precision and outstanding tribological properties such as wear resistance, seizure resistance, and low friction coefficient, all based on abundant achievements and experience, with short delivery times. In particular, coatings from the Seltes brand, such as CrN-based coatings (Seltes X, N) as alternatives to Cr plating and Seltes DLC, which have excellent adhesion even under high surface pressure, are highly regarded in plastic molding molds, press molds, automotive parts, and high-precision sliding components. We also conduct various evaluations of metal surfaces and thin films, as well as defect analysis, using surface cleanliness measurement instruments like Corona Surf.
