Spi CMS160726107 Vertical Dial Test Indicator Nist

Product Description

The SPI CMS160726107 is a vertical dial test indicator designed for precision measurement in machining, metrology, and inspection applications. It covers a measurement range of 0 to 0.03 inches with a dial graduation and accuracy of 0.0005 inches, making it suitable for detecting fine surface variation and runout. The dial reads 0-15-0 on a 1.25-inch white face with a satin chrome finish. Movement is fully jeweled for long service life and consistent sensitivity. A NIST traceability certificate is included, supporting quality-system compliance requirements. Machinists, toolmakers, metrologists, and quality technicians are the primary users.

This indicator is suited for use on surface plates, height gages, and machine tool setups in both shop-floor and inspection-room environments. The dovetail mount and included universal clamp allow flexible positioning across a wide variety of fixtures and arms. It ships in a fitted case with all accessories needed to begin use immediately, including two contact points, dovetail extensions, a height gage bar, and a universal clamp.

Compatibility

Designed for use with standard dovetail-style indicator holders, arms, and height gage attachments common in machine shop and inspection environments. Dovetail extensions in 5/32-inch and 3/8-inch sizes are included to expand mounting options.

Installation Notes

Mounting and zeroing should be performed by a qualified machinist or metrologist familiar with dial indicator setup practices. Secure the indicator firmly in a dovetail holder or clamp before zeroing to prevent drift during measurement. Avoid applying side loads to the contact point spindle, as this can affect accuracy and damage the jeweled movement. Periodic recalibration against a known reference is recommended to maintain measurement traceability.
