GWM-4 (GXTM-4) Internal Vessel Coating Integrity Tester (Welcome to watch the video for usage instructions)

           

   

Application and Principle:

The GXTM-4 Coating Integrity Tester for Cans is used to inspect the integrity of the internal coating within cans (density of internal coating, electrical value). Incomplete internal coating can lead to corrosion of the contents, affecting product quality and storage. The Coating Integrity Tester for Cans is a standard for evaluating can quality in the can-making industry. When paired with a can lid fixing device and vacuum equipment, it can also measure the integrity of the internal coating within the "can lid." Widely used in industries such as food, beverages, milk powder, soft drinks, can manufacturing, and coatings.

The testing principle involves applying voltage to the inside and outside of a container filled with electrolyte, measuring the current value. If the internal coating is incomplete (either not dense or damaged), the current value will be high. Any value over 30mA is considered不合格, and the coating defects will also exhibit small bubbles.

Technical Specifications:

Voltage measurement: 6.3V, measurement range: 0-500mA, graduation: 0.01mA, accuracy: 1%

Configuration: The integrity tester for coating inside drums includes: Main display controller, drum body clamp, 6.3 mA standard test resistor.

To measure the integrity of the coating on the "can lid," the following accessories are required: can lid fixing device; vacuum equipment.

Can Seal Coating Fixation Device; Our developed can seal coating fixation device is equipped with vacuum equipment, so there's no need for the customer to purchase additional vacuum equipment. Furthermore, our can seal coating fixation device and the vacuum equipment it comes with are equipped with a pressure-regulating protection device. Whether the customer has vacuum expertise or not, the pressure-regulating protection device ensures the safety of the fixation device, preventing any damage.

Large diameter test fixtures; standard-mounted bracket fixtures are suitable for circular-oval and other shapes.
