AuditCheck™ Performance Verification System

AuditCheck™ Performance Verification System

N/A In bulk applications where material is moving rapidly, it's difficult to periodically test a metal detector by inserting test pieces in the product flow. This is where the AuditCheck™ option comes in. AuditCheck™ automatically passes an air-driven test shuttle through the metal detector and compares both the magnetic and conductive signals to calibrated levels. This operation goes far beyond a simple go/no-go test. Because signal levels are measured and compared to acceptable levels, problems can be identified before they happen. Since the AuditCheck™ is integral to the Apex™ software, it is failsafe and a complete record of all tests is available for full traceability.
