CRPM series corrosion resistance potential measuring instrument

The National Nonferrous Metals and Electronic Materials Analysis and Testing Center has developed a series of corrosion resistance potential measuring instruments, which are mainly used to measure aluminum alloy hot extrusion profiles for construction (hereinafter referred to as profiles) whose surfaces have been anodized, electrolytically colored or organically colored. And the corrosion resistance of aluminum alloy anodization and organic coating. Other aluminum alloy processing materials with the same purpose and surface treatment can also be used as a reference. It is also suitable for evaluating the corrosion resistance of surface coatings of other metal materials. The instrument has the characteristics of easy operation, stable and reliable operation, high test accuracy, smooth liquid addition, and accurate data.
