Ensure the integrity of internal can coatings with the ER-1 Enamel Rater. This advanced tool offers fast and precise measurements for quality control in the food and beverage packaging industry.

Accurate Coating Measurement

The ER-1 Enamel Rater quickly measures the integrity of enamel coatings inside containers. It automatically starts measurement when the electrical probe contacts the solution, ensuring reliable results.

User-Friendly Interface

Featuring a 7” LCD touchscreen, the ER-1 is designed for ease of use. It offers multiple measuring modes, including 4-second, continuous, and user-defined, making it adaptable to various testing needs.

Durable and Versatile

Constructed for durability, the ER-1 is suitable for testing a range of containers, including 2-pcs cans, 3-pcs cans, aerosol cans, tubes, and various covers. It also provides RS232 output for efficient data management.

Measuring principle:
The instrument applies a constant micro-voltage across the can’s body and an electrode immersed in the electrolytic water filled, and measuring the resulting current. Voltage during the test is 6.3 V DC. The operating range is 0 to 300 milliampere with an accuracy of resolution of 0.01 milliampere.

The cover support comprises a container mounted on a pivot. The cup is beveled to make a tight seal on the can cover. The electrode and the connection to the vacuum in the container are mounted. On the base, a valve for creating a vacuum and a movable arm, complete the electrical circuit when the assembly is inverted.

Measuring modes:

• • 4 second mode: The reading will be displayed only at 4 seconds.
  • Continuous mode: The changing current reading will be displayed during all the measuring time. It will not stop displaying until operator’s order.
  • User-defined mode: The reading will be displayed at the setting time by operator.

Characteristics:

• Test the coverage of the enamel coating inside canned food, beverages, tubes and aerosols as well as the different types of covers.
• Displays an index of the amount of metal exposed by incomplete enamel coverage.
• Integrated 7” LCD touch screen and user friendly interface offers the easy-operation.
• Operator, product, sample & batch number can be memorized
• RS 232 output.
• User self-calibration.
• Detect the exposed position of metal.
