The standard digital depth caliper is a precision measuring instrument used to detect the depth of holes, slots, and grooves, with a resolution of 0.01 mm or 0.0005”. Made of hardened stainless steel, it features a shockproof PVC housing, a 100 mm bridge, and an 8.5 mm contact point—ideal for demanding industrial environments. Used by technicians and mechanical engineers, it is commonly employed in machine shops, quality control labs, and sectors such as automotive, precision mechanics, and aerospace. Thanks to the mm/inch, hold, and zero functions, it ensures versatility and reliability at every stage of measurement.
