Metal Detector Calibration Services

What is Metal Detector Calibration?

Metal detector calibration tests and certifies that your industrial detector reliably identifies metal contamination of the types and sizes, and in the locations, specified in your product safety plan. The process uses metal or metal alloy test pieces matched to your facility's detection requirements. Each test piece passes through the detector's opening, or aperture, multiple times to confirm consistent detection.

A Testing Program Built Around Your HACCP Plan

Your metal detector testing program should reflect your production line, products, and packaging. We work with your HACCP team to set test parameters for your equipment and the metal contamination risks identified in your plan. If you haven't defined those parameters yet, we can recommend starting points to help you establish a testing program.

Test parameters developed with your HACCP team typically include:

• Metal type: Steel, stainless steel, brass, or aluminum

• Test piece size: From standard reference sizes down to less than 1mm, with sizing guided by your product type (wet or dry) and the detector's aperture height

• Shape: Sphere, puck, stick, wire/rod, card, or other relevant shapes

• Location within the detection aperture: Center, or other positions relevant to your product flow

• Line speed: Typically tested at the detector's current operating rate

• Product proximity: Standalone testing, or testing over, under, beside, or inside actual product/packaging

Working with your team keeps your calibration program aligned with your actual production conditions, contamination risks, and HACCP requirements, rather than relying on a generic test.
