Metal detector test balls are made for gravity-fed and pipeline detection systems, where a flat card or wand will not travel with the product. Our 1" metal detector test balls are molded into a 1 inch sphere that works with any gravity-assisted system, in a material built not to shed. Each ball is made to order with a certified ferrous, non-ferrous or stainless steel 316 contaminant from 0.5mm to 6.5mm, color coded so the contaminant type is clear at a glance, and supplied with a Certificate of Conformity. For conveyor lines, see test wands, test cards and test cylinders and pucks, or use flexible test whips for long runs. Browse all metal detector test pieces, see how to get a copy of your certificate, or request a quote for a custom size.
