The Mitutoyo ABSOLUTE digital disc micrometer uses flat discs and non-rotating spindle constructed of hardened steel in own Japanese facilities to measure lengths of spur and helical gears. 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.
Features:
- ABSOLUTE (ABS) linear scale eliminates the need for setting the origin point every time the micrometer is powered on
- Elimination of overspeed errors allows higher measurement reliability and repeatability
- 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
- IP54 protection resists debris, dust and water
