Starrett 1015MB-150 Millimeter Reading Portable Dial Indicator 1015MB-881J Thickness Gauge Without Case, 0.01mm Graduation, 25mm Range, 0-100 Dial Reading

After inserting work between the measuring contacts, releasing the lever will cause the spindle to contact the work, giving an accurate size reading because measuring pressure is independent of the user. Indicators have jewel bearings and continuous dials. The contact edges are radiused to prevent the work from being marred or deflected. The flat contact area measures 6.3mm in diameter and is 0.125mm thick.
