The Mitutoyo standard diameter-sized, single-revolution dial indicator offers complete measurement with one sweep of the hand to eliminate miscounting errors on an easy-to-read scale. Conforms to ANSI/AGD standards.
Standard One Revolution-Series 2
Features & Benefits
The Mitutoyo one revolution dial indicator allows the entire spindle travel, or range, with one sweep of the hand. This eliminates the possibility of reading errors from miscounting multiple hand revolutions. The one-revolution indicator is ideal for determining if a spindle range is within or outside a tolerance. The jeweled bearing provides great wear resistance and low friction movements for smooth, precise operations. The stem and spindle are constructed of hardened steel for better durability. The glare-free crystal has a scratch-resistant coating for clearer readings and better durability. A revolutionary offset spindle bushing design provides trouble-free stem clamping and a longer clamping range.
