Spi CMS160713014 Electronic Drop Indicator 1 in Digital

Product Description

The SPI CMS160713014 is a digital electronic drop indicator designed for precision dimensional measurement in machining, inspection, and quality control applications. It measures displacement up to 1 inch (25.00 mm) with a resolution of 0.0001 inches (0.002 mm) and an accuracy of 0.0006 inches (0.015 mm). The center lug flat back mount allows secure attachment to magnetic bases, surface plates, and indicator holders. A CR2032 battery powers the digital display, which reads in both inch and metric units. This tool is appropriate for machinists, quality technicians, and tool-room professionals who require traceable measurement documentation.

This drop indicator is suited for surface plate inspection, machine tool setup, runout checking, and flatness verification in both shop floor and laboratory environments. The NIST traceability certification makes it appropriate for facilities operating under ISO, AS9100, or similar quality management standards. The 3/8 inch stem diameter is compatible with standard indicator holders and dovetail clamps used in most machine shop setups.

Key Features

• Digital display reads in inch and metric units for dual-unit workflows
• Accuracy of 0.0006 inches (0.015 mm) for reliable precision measurement
• Resolution of 0.0001 inches (0.002 mm) for fine displacement detection
• Center lug flat back mount compatible with standard magnetic bases and holders
• NIST traceability certification included for quality management compliance
• CR2032 battery powered with no external power source required

Compatibility

The 3/8 inch stem diameter fits standard indicator holders, dovetail clamps, and magnetic base fixtures commonly used in machine shop and inspection setups. Designed for use with surface plates, mill tables, and lathe setups where a center lug flat back mount is specified.

Installation Notes

Mount the indicator using a compatible holder that engages the 3/8 inch stem and center lug securely before taking measurements. Ensure the measuring force of 1.50 N is not exceeded by overextending the spindle during setup. Zero the display after securing the indicator in position and before recording any measurement data. Handle with care to avoid dropping the unit, as impact damage can affect calibration and void the NIST traceability certification.
