The Z313 Enamel Rater measures the lacquer integrity of metal food cans boasting a typical throughput speed of 3 food cans per minute, using our unique static fill, rate and extract philosophy. Read More


The Z313 Enamel Rater measures the lacquer integrity of metal food cans. The gauge can be specified for conveyor loaded (automatic) or fully line fed (in-line) operation. Both systems can be specified with Torus’ optional LSM / ISG recognition camera module for colour spray dot identification, ensuring SPC data output is tagged with the relevant traceability for effective remedial actions.
