• Measures “root tangent length” of spur gears and helical gears.
  • Determination of the root tangent length: refer to “Quick Guide to Precision Measuring Instruments”.
  • Non-rotating spindle type.
  • Measurable range of gear pitch: 0.5 to 6 module (series 227: 0.4 to 3 module).
  • Equipped with Ratchet Stop for constant measuring force.
  • Supplied with a setting standard (except for 0-25mm/0-1” measuring range).

Quickmike

Provides a speedy spindle feed of 10mm per thimble rotation, which enables widely differently sized features
to be measured quickly.

Quickmike type with adjustable  measuring force
Digimatic micrometer dedicated to applications requiring
a constant/low measuring force such as measuring wire,
paper, and plastic/rubber parts.
