The Mitutoyo digital disc micrometer uses flat discs and non-rotating spindle made with hardened steel in own Japanese factory to measure lengths of spur and helical gears. The flatness and thinness of the discs allow for reliable measurements in tight spaces. The non-rotating spindle reduces torque on parts being measured and prevents workpiece deformation and wear. A ratchet-stop mechanism provides uniform pressure on a workpiece for precise, repeatable measurements. Readings are displayed on an easy-to-read LCD readout.
- Measuring surfaces are constructed of carbide to reduce wear
- Ratchet mechanism provides an audible cl-ick to ensure measurement is performed at a constant force
- SPC output function allows for quick and easy data management in real time
- Functions include Origin Set, Zero/ABS Setting, Data Hold, Data Output, Function Lock, and inch/mm conversion (on inch/metric models only)
- Alarm: Low Voltage, Counting Value Composition Error
- Satin chrome finish on the sleeve and laser etched measurements on thimble for easier reading
- Frame has a non-slip finish for better grip in shop environments
