Spi CMS160725030 Dial Caliper 6 in 0.001 Graduation Nist

Product Description

The SPI CMS160725030 is a stainless steel dial caliper with a 6-inch measurement range and 0.001-inch graduation, designed for precision dimensional measurement in trade and industrial environments. The caliper reads outside, inside, depth, and step measurements from a single tool, with the dial advancing 0.1 inches per revolution. Accuracy is rated at plus or minus 0.001 inch. The purple dial face improves readability under shop lighting. This tool is factory calibrated and ships with a NIST traceability certificate, making it suitable for use in quality-controlled work environments.

This caliper is appropriate for any trade or industrial application requiring repeatable, precise linear measurement. HVAC technicians, pipefitters, machinists, and quality control personnel commonly use dial calipers for checking pipe diameters, fitting clearances, component dimensions, and step depths. The 1.57-inch jaw length provides adequate reach for most common fastener, fitting, and part inspection tasks. The included fitted case protects the caliper during transport and storage between jobs.

Installation Notes

No installation is required for this measuring instrument. Before use, verify the caliper zeroes correctly with the jaws fully closed and inspect the dial for free movement without binding. Clean jaw contact surfaces before each measurement session to prevent debris from affecting accuracy. Recalibrate or return for recertification if the tool is dropped or subjected to impact.
