Mitutoyo 500-181-30 Electronic Caliper 6 Inch IP67

Product Description

The MITUTOYO 500-181-30 is a digital electronic caliper from the 500 ABSOLUTE Digimatic series, designed for precise dimensional measurement in trade and industrial settings. Built with a hardened stainless steel beam and stainless steel knife-edge jaws, it delivers a maximum measurement range of 6.0 inches (150 mm) with IP67-rated protection against dust and water ingress. The sliding jaw adjustment provides smooth, repeatable operation. Powered by a single SR44 silver oxide battery (included), it suits machinists, pipefitters, and precision measurement work on the shop floor or in the field.

This caliper is suited for measuring outside diameters, inside diameters, depth, and step dimensions across residential, commercial, and industrial applications. The knife-edge jaw style allows measurement in tight or irregular profiles. It is commonly used by HVAC technicians for component sizing, plumbers for pipe fitting verification, and fabricators requiring repeatable dimensional checks. The caliper ships with the battery, a protective case, and the instrument itself, making it ready for immediate use on the job.

Installation Notes

No installation is required for handheld calipers. Before use, inspect jaw faces for burrs or debris that could affect measurement accuracy.

Battery replacement uses a standard SR44 cell; power down the caliper before opening the battery compartment.
