6" digital caliper

This Hi-Tech Diamond 6″ digital caliper is accurate to +/-.01mm, measures inside and outside diameters, and can be quickly toggled between inches and millimeters. Calipers make precise measurements of beads, gems, cabochons, bezels and mounts. Hi-Tech Diamond 6" digital calipers are professional quality, with hardened-steel jaws and prongs. Why does hardened-steel matter? Non-hardened jaws and prongs will eventually indent or become abraded resulting in measurement inaccuracies.  Slots are ground and polished, not merely milled out, for a smoother sliding motion. Each and every caliper goes through a 15-point accuracy test. Features 0-6" range +/-.01mm accuracy Locking screw Stainless steel frame LCD display screen Zero Function allows setting zero at any position, for making incremental measurements, as well as performing reverse and deviation measurement techniques. One-button change from inches to millimeters Battery and case included 30-day warranty
