Spi CMS160714027 Electronic Drop Indicator 0.5 in

Product Description

The SPI CMS160714027 is a digital electronic drop indicator designed for precision dimensional measurement in machining, inspection, and quality control applications. It features a digital display with a maximum measurement range of 0.5 inches (12.70 mm) and an accuracy of 0.0008 inches (0.020 mm). Resolution is 0.0005 inches (0.010 mm), giving technicians fine discrimination for surface variation, runout, and feature deviation checks. The center lug flat back mounting style allows secure attachment to magnetic bases and indicator holders common in machine shop and metrology environments. A NIST traceability certification is included, supporting documentation requirements for regulated inspection workflows.

This drop indicator is suited for use in precision machine shops, tool rooms, production inspection stations, and quality assurance labs. It is appropriate for both inch and metric measurement work. The CR2032 battery powers the digital display, and the 3/8-inch stem diameter fits standard indicator holders and dovetail mounts used across most shop environments. Machinists, metrologists, and quality control technicians are the primary installers and users of this instrument.

Key Features

• Digital display with 0.0005-inch (0.010 mm) resolution for fine measurement discrimination
• Accuracy of 0.0008 inches (0.020 mm) across the full 0.5-inch range
• Reads in both inch and metric units
• Center lug flat back mounting for compatibility with standard magnetic bases and holders
• 3/8-inch stem diameter fits common indicator clamps and dovetail fixtures
• NIST traceability certification included for regulated inspection documentation
• CR2032 battery for reliable, widely available power

Compatibility

Designed for use with standard indicator holders, magnetic bases, and dovetail-style mounts accepting a 3/8-inch stem diameter drop indicator.

Installation Notes

Installation is performed by machinists or quality control technicians using a standard indicator holder or magnetic base. Ensure the stem is secured firmly in the clamp without over-tightening, which can distort the stem and affect measurement accuracy. Zero the indicator after mounting and before taking measurements. Handle the contact point and spindle with care to avoid damage to the precision measuring components.
