Our test cards are made in colour coded high visibility acrylic, with a standard size of 80 x 40 mm with rounded corners. The cards are available in three thicknesses, the thickness depends of the contaminant.
A 5mm thick test card will take up to a 3.5mm contaminant or 10mm thick up to 7.5mm contaminant.
Each test card is issued with a certificate of conformity confirming the exact size and composition of the contaminant, and the card is engraved with the contaminant details and certificate number. These cards are typically used on bagged or bulk product metal detector applications.
