Series 369

Disc Micrometers – Non-Rotating Spindle

Mitutoyo Digimatic Disc Micrometer with hardened-steel flat discs and non-rotating spindle for high-accuracy spur & helical gear measurement. Features 20 mm discs, carbide faces, SPC output, and ±0.0002” accuracy.

Features
  • Flat disc anvils (20 mm / 0.787") measure root tangent lengths of spur & helical gears
  • Non-rotating spindle minimizes torsion, deformation, and wear
  • Carbide-tipped measuring surfaces resist wear for extended accuracy
  • Ratchet-stop mechanism applies constant measuring force for repeatability
  • SPC output for real-time data transfer and analysis
  • Functions: Origin Set, Zero/ABS, Hold, Data Output, Function Lock, inch/mm conversion (on in/mm models)
  • Satin-chrome sleeve with laser-etched thimble scale; non-slip frame grip
  • Includes standard bar (except small-range models)
  • Supplied in a fitted plastic case
  • Available in Metric and Inch/Metric models
