Spi CMS160725025 Dial Caliper 18 Inch Stainless Steel

Product Description

The SPI CMS160725025 is an 18-inch range dial caliper designed for precision measurement in trade, industrial, and inspection applications. Built from stainless steel with a satin chrome finish, it delivers outside, inside, and depth measurements with a dial graduation of 0.001 inches and an accuracy rating of 0.002 inches. The white dial face provides clear readability, and the adjustable bezel allows the technician to zero the dial at any position. At 2 pounds, it is a full-size precision tool intended for professional use by machinists, pipefitters, HVAC technicians, and quality control personnel who require reliable, repeatable measurement across large workpieces.

This caliper is suited for both shop-floor and field measurement tasks where an 18-inch range is required. The 3.125-inch jaw length accommodates wide workpieces and deep inside measurements. Each revolution of the dial advances the reading 0.1 inches, keeping tracking straightforward across the full 18-inch span. Its NIST traceability certification and short-form calibration certificate make it appropriate for environments where documented measurement traceability is required, including quality assurance, fabrication, and regulated inspection workflows.

Key Features

• 0.001-inch dial graduation with 0.002-inch accuracy for precise readings
• Stainless steel body and jaws resist corrosion and wear in demanding shop environments
• Adjustable bezel enables quick zeroing at any measurement point
• Measures outside, inside, and depth dimensions from a single tool
• NIST traceability certification and short-form calibration certificate included

Compatibility

Designed as a general-purpose precision measuring instrument suitable for use in machining, fabrication, HVAC, plumbing, and industrial inspection applications requiring an 18-inch dial caliper.

Installation Notes

This instrument requires no installation. Handle with clean, dry hands to avoid contaminating the measuring surfaces and dial mechanism. Store in the provided case when not in use to protect the calibration and finish. If the caliper has been dropped or subjected to impact, have it recalibrated before returning it to service.
