GWM-4 (GXTM-4)罐内 Coating Integrity Tester(Welcome to view the video for usage instructions)

Usage and Principle:

GXTM-4 Internal Coating Integrity TesterUsed to inspect the integrity of the internal coating inside cans (density of internal coating, electrical value). Incomplete internal coating inside cans can lead to corrosion of the contents, affecting product quality and storage. The internal coating integrity tester is the 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 inside the "can lid". Widely used in industries such as food, beverages, milk powder, soft drinks, can making, coatings, etc.

The testing principle involves applying voltage to the inside and outside of a container filled with electrolyte, and measuring the current value. If the inner coating is incomplete (either not dense or damaged), the current value will be significantly high. A value over 30mA indicates non-compliance, and the areas of the coating that are not up to standard will also exhibit tiny bubbles.

Technical Specifications:

Voltage measurement: 6.3V, Measurement range: 0-500mA, Graduation: 0.01mA, Accuracy: 1%

Configuration: The tank coating integrity tester includes: Main display controller, tank body fixture, 6.3 mA standard test resistor.

To measure the coating integrity inside 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 is no need for customers to purchase additional vacuum equipment. Moreover, our can seal coating fixation device and the vacuum equipment it comes with are equipped with a pressure regulation protection device. This ensures that regardless of whether the customer has vacuum expertise, the pressure regulation protection device will safeguard the can seal coating fixation device, preventing any damage.

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