Digital Aluminum Collapsible Tubes Internal Coating Continuity Tester

Machinery description

It is mainly used to test the continuity of aluminum collapsible tubes’ internal coating.

The equipment has attractive appearance, digital display. It is easy to take and operate. Its accuracy can be up to 0.1mA. This highly improves the quality control of internal coating. It is a good choice for aluminum collapsible tubes company to improve quality of products.


Principle

The internal coated tubes is full of copper sulfate liquor. Put the sliding electrode into the liquor. The tube touches the electrode with V-grooves. Then the stable 5±0.5V direct current is used between sliding electroplate and tube. The current is in direct proportion to tube’s uncovered surface area. If coating is not continuous, the copper sulfate liquor will response under the influence of electrolytic current. The leaky parts will appear black deposited copper. The device will directly indicate the nude position and area.
