The Mitutoyo mechanical caliper type micrometer delivers precise measurements on recessed features which regular micrometers are unable to achieve.
Series 143
Caliper-Type Micrometers
Features & Benefits
The Mitutoyo 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 for easy one-handed measurements.
- Available in Metric or Inch models
- Ratchet stop mechanism provides an audible click to ensure measurement is being performed at a constant pre-set force
- Carbide-tipped measuring tips resist wear for better accuracy over time
- Frame has a baked enamel finish for more durability
- Satin chrome finish on the sleeve and laser etched scale on thimble for easier reading
- Includes a standard bar except for 0-25mm / 0-1” models
- Supplied in a plastic, fitted case
