Spi CMS160714026 Electronic Drop Indicator 2 in Digital

Product Description

The SPI CMS160714026 is a digital electronic drop indicator designed for precise dimensional measurement in machining, inspection, and quality-control applications. It offers a measuring range of 0 to 2 inches (0 to 50.00 mm) with a resolution of 0.000050 inches (0.0010 mm) and a stated accuracy of 0.000250 inches (0.0060 mm). The digital display provides clear, direct readout in both inch and metric units. The center lug flat back mounting configuration suits standard magnetic-base and surface-plate setups. Installation and operation are handled by machinists, metrologists, and quality technicians.

This indicator is suited for surface plate inspection, machine tool setup, and fixture verification in both shop-floor and metrology lab environments. The flat back and center lug design allow the indicator to seat securely in a wide range of indicator holders and transfer-stand fixtures. The 3/8-inch stem diameter fits the most common collet-style holders used in production and toolroom settings. The unit ships with a NIST Traceability Certification, making it appropriate for quality systems that require documented measurement traceability.

Key Features

• Digital display with 0.000050-inch (0.0010 mm) resolution for high-precision readout
• Dual-unit readout in inches and metric (mm) selectable on the indicator
• Center lug flat back mounting for compatibility with standard indicator holders
• 3/8-inch stem diameter fits common collet and dovetail-style holders
• NIST Traceability Certification included for documented quality compliance
• Powered by CR2032 coin-cell battery for convenient field and bench use

Compatibility

Designed as a standard-fit digital drop indicator for use with indicator holders, magnetic bases, and transfer stands that accept a 3/8-inch stem diameter and center lug flat back configuration.

Installation Notes

This indicator is installed and serviced by machinists, toolroom technicians, and quality-control personnel. Secure the 3/8-inch stem in a collet holder or indicator stand before zeroing the instrument. Avoid exceeding the 2-inch measuring range, as over-travel can damage the internal mechanism. Replace the CR2032 battery when the low-battery indicator activates to maintain measurement accuracy.
