Spi CMS160725002 Vertical Dial Test Indicator 0.0001 in

Product Description

The SPI CMS160725002 is a vertical-style dial test indicator designed for precision measurement applications in machining, metrology, and inspection work. It features a fully jeweled movement with a 0.0001 inch graduation and a maximum measurement range of 0.008 inches per revolution. The 1.25 inch white dial provides high-contrast readability under shop conditions. A NIST traceable short-form certificate of calibration is included, making this indicator suitable for controlled measurement environments where traceability documentation is required. This tool is installed and used by machinists, tool-and-die technicians, and quality control professionals who need reliable, repeatable surface deviation readings.

This vertical dial test indicator is suited for use on manual mills, surface plates, CMM setups, and height gage applications in both production and inspection environments. The dovetail mount accommodates standard 5/32 inch and 3/8 inch dovetail extensions, providing flexible positioning across a wide range of fixturing setups. The universal clamp included in the kit further expands mounting options. The satin chrome finish resists corrosion in typical shop environments.

Key Features

• Fully jeweled movement for smooth, accurate needle travel and extended service life
• 0.0001 inch graduation over a 0.008 inch range for high-resolution surface deviation measurement
• Dovetail mount with 5/32 inch and 3/8 inch extension compatibility for versatile positioning
• NIST traceable calibration certificate included for quality-controlled inspection use
• 1.25 inch white dial with 0-5-0 bidirectional reading for direct deviation readout
• Satin chrome finish for durability in machining and inspection environments

Compatibility

Designed for use with standard dovetail-mount indicator holders, height gage bars, and universal clamps common to manual and CNC machine tool setups. The included 5/32 inch and 3/8 inch dovetail extensions are compatible with most commercially available indicator arms and surface gage holders.

Installation Notes

This indicator is installed by machinists and metrology technicians using standard dovetail holders or the included universal clamp and height gage bar. Before mounting, ensure the workpiece and reference surface are clean and free of chips or debris that could affect measurement accuracy. Do not overtighten the dovetail clamping mechanism, as excessive force can damage the indicator body or affect calibration. Store in the fitted case when not in use to protect the jeweled movement and maintain calibration integrity.
