Medical tubing, transparent hoses, plastic tubes, copper tubes, and other precision tubing can experience diameter variation, ovality, local bulges, and dimensional deviations during extrusion or forming due to material temperature, line speed, die condition, and cooling. Based on telecentric optical technology, DALA Metrology provides non-contact in-line measurement for transparent, translucent, and opaque tubing, including outer diameter, width, thickness, ovality, and local lump/neckdown inspection.
