Adjustable Measuring Micrometers

  • Digimatic micrometer dedicated to applications requiring a constant/low measuring force such as measuring wire, paper, and plastic/rubber parts.
  • Ratchet mechanism in the thimble applies constant force to workpiece.
  • Compact and easy to handle.
  • Measuring force is adjustable (in steps) to suit various kinds of workpiece.
  • High-accuracy measurement can be performed even by unskilled operators due to the repeatability of the automatically applied measuring force.
  • Non-rotating spindle.
  • Measuring faces: Carbide

Constant-measuring-force mechanism

Adjustable Measuring Micrometers

  •  Measuring force is generated by the action of trapping a workpiece between the spindle face and the anvil.
  • The constant-force unit applies the specified measuring force.
  • When the preset measuring force is reached, the count on the LCD is automatically held and the hold symbol appears.

(To cancel the hold, reverse the thimble more than 1/10 revolution and press the hold button.)
