Mitutoyo 500-178-30CAL Electronic Caliper 0-6 in Nist

Product Description

The MITUTOYO 500-178-30CAL is a stainless steel electronic caliper from the 500 ABSOLUTE Digimatic series, designed for precision dimensional measurement in trade and metrology applications. It covers a measurement range of 0 to 6 inches with a resolution of 0.0005 inches and an accuracy of 0.0010 inches. The caliper features an IP67 ingress protection rating, making it resistant to coolant and dust in machine-shop and field environments. It ships NIST-traceable calibration documentation, which satisfies quality-system and inspection requirements. A licensed metrologist, machinist, or quality-control technician is the typical end user for this instrument.

The 500-178-30CAL is suited for outside diameter, inside diameter, depth, and step measurements on parts encountered in HVAC fabrication, plumbing rough-in inspection, electrical conduit work, and general precision trade work. The knife-edge jaw style allows access to narrow grooves and shoulders that standard flat jaws cannot reach. The caliper is appropriate for both shop bench use and jobsite quality checks where a rugged, calibrated instrument is required.

Key Features

• IP67-rated stainless steel body and jaws resist coolant, dust, and debris
• 0.0005 inch resolution with 0.0010 inch accuracy across the full 0 to 6 inch range
• NIST-traceable calibration certificate included for quality-system compliance
• Knife-edge jaws measure outside diameter, inside diameter, depth, and step in a single tool
• Data output port enables direct transfer to SPC software or data loggers
• Thumb-wheel jaw adjustment for controlled, repeatable positioning
• Includes depth measurement rod and inside diameter jaws as integrated features

Compatibility

Designed as an OEM-style precision caliper in the MITUTOYO 500 ABSOLUTE Digimatic series; compatible with SR44 silver oxide batteries and standard SPC data-output accessories designed for the Digimatic interface.

Installation Notes

Electronic calipers require no power-down procedure for installation but should be zeroed before first use following the manufacturer calibration documentation included in the case. Avoid exposing the data output port to fluids beyond the IP67 rating limits. Battery replacement uses a single SR44 silver oxide cell; handle the battery compartment with care to avoid contaminating the contact surfaces. Verify NIST calibration certificate documentation is filed per your quality management system requirements at incoming inspection.
