Spi CMS160713016 Electronic Drop Indicator 1 in

Product Description

The SPI CMS160713016 is a digital electronic drop indicator designed for precision dimensional measurement in industrial and machine-shop environments. With a maximum measurement range of 1.0000 inch (25.00 mm) and a resolution of 0.000050 inch (0.0010 mm), it delivers fine measurement capability for setup, inspection, and quality-control work. Accuracy is rated at 0.000200 inch (0.0050 mm). The indicator features a digital display and a center lug flat back mounting style, making it compatible with standard indicator holders and magnetic bases. A NIST traceability certification is included. Licensed metrology technicians and precision machinists are the primary users.

This drop indicator is suited for use on surface plates, comparator stands, and machine tool setups in both production and tool-room environments. The digital readout supports readings in both inch and metric units, reducing conversion errors during mixed-unit work. The center lug flat back configuration fits common universal indicator holders. Measuring force is rated at 1.50 N, making it appropriate for contact measurement on finished or semi-finished surfaces where excessive stylus pressure could affect results.

Key Features

• Digital display with inch and metric readout modes
• Resolution of 0.000050 inch (0.0010 mm) for fine measurement tasks
• Accuracy of 0.000200 inch (0.0050 mm)
• Center lug flat back mounting for standard indicator holders and magnetic bases
• NIST traceability certification included
• CR2032 battery; 3/8-inch stem diameter

Compatibility

Designed for use with standard indicator holders, comparator stands, and magnetic base arms that accept a 3/8-inch stem diameter drop indicator.

Installation Notes

Mount the indicator in a holder or magnetic base that securely grips the 3/8-inch stem before applying any measurement load. Ensure the stem is fully seated and the locking mechanism is tightened before zeroing the display. Do not exceed the maximum measurement range of 1.0000 inch to avoid damage to the internal mechanism. Replace the CR2032 battery when the low-battery indicator appears to maintain display accuracy.
