CanNeed-DER-400 is the industry standard. The new CanNeed Enamel Rater DER-400 instrument test the coverage of the enamel coating inside food and beverage cans, aerosol-cans and also different kinds of ends. It displays an index of the amount of metal exposed by incomplete enamel coverage on a clear, easily read digital LED.
Advantages:
1 Faster to detect the exposure of metal
2 Optimized electric design, more sensitive, reliable and accurate up to 0.01mA
3 Optimized clamp for cans with better resistance to corrosion and long lifetime
4 Keypad made of thin film, more durable and better resistance to corrosion
5 "Reverse Voltage" function enable to reverse the electrode property by one key, which generates the bubbles at exposure position, making the defect (exposure) easier to detect
