MetalCheck

MetalCheck — Professional Metal Detector Validation for Food Manufacturing MetalCheck is a purpose-built iPhone app that takes the complexity and paperwork out of metal detector validation in food production environments. Designed for food manufacturers, packers, and processors operating under HACCP-based food safety management systems, MetalCheck delivers a fully digital, audit-ready validation workflow — right from your pocket. What MetalCheck Does MetalCheck guides operators through the structured 30-test validation routine required to confirm that a metal detector is functioning correctly at its Critical Control Point (CCP). Each test is recorded individually — tap to pass, long-press to fail — with the app automatically prompting for corrective action notes on any failure. The result is a complete, tamper-evident record of every validation run, with nothing left to chance or memory. Metal Detector & Test Piece Management Set up every detector on site with full details: manufacturer, model, serial number, calibration date, location, and detection type (Full Spectrum or Ferrous in Foil). Register your certified test pieces — Ferrous, Non-Ferrous, and Stainless Steel — with sizes and serial numbers. MetalCheck records exactly which test pieces were used in each session, satisfying the traceability requirements demanded by auditors.
