The Mitutoyo Digimatic metric scale outside digital micrometer features a ratchet stop function and interchangeable anvils for measuring a wide range of workpiece sizes and material types.
Features & Benefits
The Mitutoyo digital ratchet stop outside micrometer is ideal for measuring metal and non-metal workpieces by controlling the amount of spindle force. A ratchet-stop mechanism provides uniform pressure on a workpiece for precise, repeatable measurements. Interchangeable anvils allow for measuring a wide range of workpiece sizes. Measurements are displayed on a coolant-proof, easy-to-read LCD readout.
- Ratchet mechanism provides an audible click to ensure measurement is being performed at a constant pre-set force
- SPC output function allows for quick and easy data management in real time
- Functions include Origin Set, Zero/ABS, Hold, Function Lock, Data Output, and inch/mm conversion (on inch/metric models only)
- Alarm: Low Voltage, Counting Value Composition Error
- Zero-setting standards bar for each range is included
- Scale is laser etched on thimble for easier, faster reading
- Carbide facing on the spindle resists wear to keep surfaces flatter with longer accuracy
- Speeder is always available for quick rotation of the spindle
- IP65 protection permits use in environments exposed to cutting oil, dust, etc. on models up to 12” / 300mm*
- Supplied in fitted plastic case
*Anti-corrosion treatment is required after use
