ER-1 Enamel Rater

AT2E ER-1 Enamel Rater offers a fast and accurate method to measure the integrality of internal coating of containers. A measuring will be started automatically when the electrical probe is inserted and contacts the solution inside the container.
 
The position of exposed metal can be detected visually by pressing the “REVERSE” button. Bubbles of gas come out on the exposed points.

Measuring principle

Theinstrument applies aconstant micro-voltageacross thecan body andan electrode immersed intheelectrolyticwater filled, andmeasuringthe resulting current.Voltageduring the testis 6.3VDC.Theoperating rangeis 0 to300 milliamperewith an accuracy ofresolution of 0.01milliampere.
 
Thecover supportcomprises acontainer mountedon a pivot.The cup isbeveled tomake a tight sealon the can cover. An electrode andthe connectionto the vacuumin the containerare mounted. On the base,a valvefor creating a vacuumand a movable arm, complete the electrical circuit whenthe assembly isinverted.

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.

• Test the coverage of theenamel coatinginsidecanned food, beverages, tubes and aerosolsas well asthe different types ofcovers.
• Displaysan index ofthe amount of metalexposed byincompleteenamelcoverage.
