Features & Benefits

The Mitutoyo digital caliper type micrometer features jaws constructed of hardened steel with carbide measuring surfaces and a hardened steel spindle to take precise measurements on recessed features. The micrometer’s ratchet stop mechanism provides a constant measuring force on the spindle to ensure accurate, repeatable measurements. The combination of the ratchet thimble and speeder enables a rapid spindle feed when measuring extensive dimensions and easy one-handed measurements.

  • Available in Metric and Inch/Metric models
  • Ratchet mechanism provides an audible click to ensure measurement is performed at a constant force
  • Carbide-tipped measuring tips resist wear for better accuracy over time
  • Twice as long battery life than previous models improves throughput and efficiency
