The Tofd scanner consists of 3 graduated rods where up to 12 probe holder suspensions can be mounted.
By means of specific supports it is possible to equip the scanner with any kind of probe and an encoder. Probes are mounted on shoes with anti-wear grains and a water injection kit.
Coupling to the piece being inspected is guaranteed by spring support with tilting movement. The adhesion of the scanner to wall is entrusted to 4 magnetic wheels and the unit handling is manual. The inclination of the magnetic wheels allows inspection of longitudinal and circular welds up to 4 inches diameter
