Spi CMS160713023 Electronic Drop Indicator 2 in Digital

Product Description

The SPI CMS160713023 is a digital electronic drop indicator designed for precise linear displacement measurement in machine shop, toolroom, and quality control environments. It reads in both inch and metric units and delivers a resolution of 0.0005 inches (0.010 mm) with an accuracy of 0.0012 inches (0.020 mm) over a 2-inch (50.00 mm) measuring range. The flat back, center lug mounting style is compatible with standard indicator holders and magnetic bases. A CR2032 battery powers the digital display. NIST traceability certification is included, making this indicator suitable for calibrated inspection work. Machinists, metrologists, and quality technicians install and operate this instrument.

The CMS160713023 is suited for surface plate inspection, fixture setup, machine tool alignment, and runout measurement in both production and toolroom settings. Its dual inch and metric readout allows technicians to work to either standard without recalibrating. The 3/8-inch stem diameter fits standard dovetail and post-style indicator holders. The center lug flat back configuration allows secure, low-profile mounting on transfer stands and surface gauge arms. A measuring force of 1.50 N minimizes deflection on sensitive workpiece surfaces.

Key Features

• Digital display reads in both inch and metric units
• 2-inch (50.00 mm) measuring range starting from 0.00 mm
• Resolution of 0.0005 inches (0.010 mm) for fine measurement
• Accuracy of 0.0012 inches (0.020 mm)
• NIST traceability certification included
• Center lug flat back fits standard indicator holders and magnetic bases
• Low measuring force of 1.50 N reduces workpiece marking

Compatibility

Designed for use with standard 3/8-inch stem indicator holders, magnetic base stands, and surface gauge arms commonly used in machine shop and quality control inspection setups.

Installation Notes

Mount using a compatible 3/8-inch stem clamp or center lug holder; ensure the holder is fully tightened before zeroing the indicator. Position the spindle perpendicular to the measured surface to avoid cosine error. Install the CR2032 battery per the instrument manual before use. Handle the spindle and contact point carefully to avoid impact that could affect calibration.
