Micrometers Series 293 -Quantumike With 2mm/rev Spindle Feed

  • Faster measurements can be made with a coarse thread that feeds a 2 mm spindle.
  • Extra 2.4 year battery life.
  • Ratchet Sleeve mechanism provides constant measuring force and promotes good contact with the workpiece.

This is an IP65 micrometer offering movement four times as fast as a standard micrometer. It presents you with the following benefits: 

  • Faster measurement is achieved by using a coarser thread which feeds the spindle by 2 mm per thimble rotation.
  • Extraordinary battery life of 2,4 years
  • Outstanding accuracy
  • Ratched thimble mechanism ensures easy single-handed or stand operation. Excellent resistance against water and dust (IP65 protection level) enables this micrometer to be used in machining situations that include splashing coolant fluid.

  • Faster measurement is achieved by using a coarser thread which feeds the spindle by 2 mm per revolution of the thimble instead of the standard 0.5 mm.

  • The patented ratchet thimble mechanism* helps ensure repeatable results by transmitting microvibrations along the spindle to the contact face to provide a constant measuring force and encourage good contact with the workpiece. The ratchet works from the thimble as well as the speeder so it is always easy to use – even when making measurements one-handed.
