Starrett 09968 Electronic Drop Indicator 25mm Metric

Product Description

The STARRETT 09968 is an electronic drop indicator designed for precise dimensional measurement in tool rooms, machine shops, and quality control environments. It features an LCD display and operates on the metric system, measuring up to 25 mm with a resolution of 0.01 mm and an accuracy of 0.03 mm. The 8 mm stem diameter fits standard indicator holders and magnetic base fixtures. The unit ships with two CR2032 lithium 3V batteries included. Machinists, tool and die makers, and quality technicians use this instrument for setup, runout checks, and surface comparison work.

The 09968 suits bench inspection tasks and in-machine verification on mills, lathes, and surface plates. Its metric-only readout makes it appropriate for environments working to millimeter tolerances. The compact form factor and drop-style movement allow positioning in tight setups where dial indicators with larger bodies may not fit. Installation into a standard indicator holder takes seconds, making this a practical choice for high-turnover inspection tasks on the shop floor.

Key Features

• 25 mm maximum measurement range for general-purpose dimensional checks
• 0.01 mm resolution for fine tolerance work
• 0.03 mm accuracy across the full range
• LCD display for clear, direct digital readout
• 8 mm stem diameter fits standard magnetic base and indicator holder collets
• Includes two CR2032 lithium 3V batteries ready for immediate use

Compatibility

Designed as an OEM-style electronic drop indicator compatible with standard 8 mm stem indicator holders and magnetic base fixtures used in machine shop and inspection applications.

Installation Notes

Mounting is performed by a machinist or quality technician using a standard indicator holder or magnetic base with an 8 mm collet. Secure the stem firmly before zeroing the display to avoid measurement drift during a run. Do not overtighten the collet as this can restrict stylus movement and affect accuracy. Confirm battery installation polarity before first use.
