Metal detector validation, certification and calibration……what do these terms mean and what’s pertinent as you strive for proper use of your investment in metal detection equipment?
Validation – The daily procedure you have in place to confirm and document that your metal detectors are detecting the ferrous, non-ferrous and stainless-steel particles specified in the metal detector section of your HACCP plan; for instance, passing test wands through the detector with product every two hours.
Certification – The procedure conducted by a 3rd party to certify that your metal detectors and automatic reject devices are performing as you have documented in your daily validation procedure. This procedure is similar to your validation procedure but done by a 3rd party.
Calibration – The procedure conducted by the metal detector’s manufacturer to re-balance the metal detector transmit and receive coils and any settings to bring the metal detector back to manufacturer standards. This procedure may still be required as part of the certification service if you have older analog metal detector in use. However, current generation ProScan metal detectors feature auto-balance technology which eliminates the need for calibration service.
Advanced Detection Systems HACCP (Hazard Analysis and Critical Control Points) certified factory service technicians and certified local representatives conduct certifications on-site and are compliant with most QA programs, audits, HACCP and GMP (Good Manufacturing Practices) standards.
As your metal detector usage comes under scrutiny applied by government regulations, auditors and your customers; there is an opportunity to meet expectations and improve your competitive advantage by being proactive in certifying your metal detectors on an annual basis.
