Spi CMS160725023 Dial Caliper 300mm Stainless Nist

Product Description

The SPI CMS160725023 is a 300 mm range dial caliper designed for precise dimensional measurement in industrial, manufacturing, and metrology environments. Built from stainless steel with a satin chrome finish, it delivers an accuracy of 0.04 mm and a dial graduation of 0.02 mm per division, with 2 mm of travel per revolution of the dial. The white dial face provides high contrast for easy reading under shop conditions. This caliper ships calibrated and includes NIST traceability certification, making it suitable for quality control workflows that require documented measurement standards. Machinists, tool and die makers, quality technicians, and precision fabricators are the primary users.

This dial caliper covers four measurement modes: outside, inside, depth, and step measurement, covering the most common dimensional inspection tasks on a single tool. The 64 mm jaw length accommodates a range of workpiece geometries. The adjustable bezel allows the dial face to be zeroed at any position along the caliper travel, which is useful when measuring relative dimensions or when establishing a reference point mid-range. This tool fits production floor, inspection room, and job shop applications where analog readout is preferred over digital display.

Key Features

• 300 mm measurement range with 0.02 mm dial graduation for fine resolution
• Accuracy rated at 0.04 mm across the full range
• Stainless steel construction on body and jaws for corrosion resistance and durability
• Satin chrome finish reduces glare and surface reflection in bright shop lighting
• Adjustable bezel for on-the-fly zeroing without returning to the closed position
• NIST traceability certified and short form certified, ships calibrated
• Four measurement capabilities: outside, inside, depth, and step

Compatibility

Designed as a general-purpose dial caliper suitable for standard metrology and dimensional inspection applications requiring a 300 mm measuring range in metric graduation.

Installation Notes

This tool requires no installation. Inspection and calibration personnel should store the caliper in its case when not in use to protect the jaws and dial mechanism. Before use, verify the dial reads zero with the jaws fully closed, and adjust the bezel if needed. Avoid dropping or applying lateral force to the jaws, as this can affect rack alignment and calibration integrity.
