Starrett 3809A Horizontal Dial Test Indicator

This Starrett 3809A is a mechanical horizontal dial test indicator designed for precision measurement tasks. It offers a range of 0 in to .03 in with graduations of .0005 in. The dial size is 1.25 in and features a white face with a 0-15-0 dial reading. It includes dovetail mount attachments for versatile positioning.

Check dovetail mount compatibility and clearance

Before ordering, verify that your setup accepts the included dovetail mount attachments for secure fixturing. Ensure the contact point diameter of .156 in suits the feature geometry you intend to measure. Confirm that the horizontal orientation and total range of .03 in match the travel required for your specific inspection application.

Consistent mechanical response across

Under sustained use, the mechanical movement delivers repeatable readings across the full .03 in range per revolution. The .0005 in graduations remain legible on the white dial during extended inspection sessions. The indicator maintains its calibration integrity without electronic drift, providing stable performance for comparative checks and run-out measurements.
