ProPanel-HD is a giant digital caliper used to make inside, outside, diagonal, hole-edge, and hole-hole dimensional measurements.

This is a rugged linear measuring tool and is designed to make "on the manufacturing floor" measurements by one or two operators.
It is based on the ProScale Model 590 and is robust enough to span up to 120 inches of measuring range. It has a sliding carriage/jaw assembly that rides on 4 iGlide™ friction bearings to minimize encoder pitch and yaw.  Four removable alignment pins (shown in picture above) are included with the system for easy diagonal measurements. The optional Hole Measuring Kit containing 2 full and 1 half steel cones is available for hole measurements.
