测三价铬用比色管 镀铬溶液比色管 三价铬目视直读式比重 (CAS No.None)

Product Name:Colorimetric Tube for Trivalent Chromium in Chromium Plating Solution

English Name:Colorimetric Tube for Trivalent Chromium in Chromium Plating Solution

Aliases:Trivalent Chromium Visual Colorimetric Tube, Chromium Plating Solution Detection Tube, Visual Colorimetric Test Tube for Cr³⁺

Physical Properties:The colorimetric tube is made of high-borosilicate glass with a transparent, colorless body that resists acid and alkali corrosion and features a clear standard color scale. It can be used directly at room temperature, and the color developed is stable and fade-resistant. It is suitable for rapid visual colorimetric determination of trivalent chromium content in chromium-plating solutions containing chromic acid.

Uses:Used for rapid determination and routine process monitoring of trivalent chromium content in chromium-plating solutions in electroplating workshops. The value is read directly by visual color comparison, providing convenient and quick operation without the need for professional instruments. It helps process operators promptly understand bath performance, conductivity, and anode conditions, ensuring the quality of the chromium plating layer and maintaining bath stability.
