Spi CMS160809197 Electronic Drop Indicator 2 in

Product Description

The SPI CMS160809197 is a digital electronic drop indicator designed for precision dimensional measurement in industrial and shop environments. It features a 2-inch maximum measurement range with a resolution of 0.0005 inches (0.01 mm) and an accuracy of 0.0012 inches (0.02 mm). The center lug flat back mounting style allows secure fixture to magnetic bases, indicator holders, and transfer stands. Readings are displayed on a digital readout, supporting both inch and metric units. Machinists, quality technicians, and toolroom professionals use this instrument for runout, flatness, and surface deviation checks.

This drop indicator is suited for use in precision machining, quality control, and inspection applications. The digital display eliminates parallax error common with analog dial indicators, making it well suited for repetitive measurement tasks on the shop floor or inspection bench. The 3/8-inch stem diameter fits standard indicator holders and magnetic base collets. Its dual-unit readout makes it practical in shops working to both inch and metric tolerances.

Compatibility

Designed for use with standard indicator holders, magnetic bases, and transfer stands accepting a 3/8-inch stem diameter. No specific compatible model numbers were provided by the manufacturer for this listing.

Installation Notes

Installation and use should be performed by qualified metrology or machining personnel familiar with indicator setup procedures. Secure the stem firmly in the holder collet before taking measurements to prevent slippage and reading error. Avoid impact or lateral overload on the spindle, as this can damage the internal mechanism. Replace the CR2032 battery when the low-battery indicator appears on the display to maintain accuracy.
