• Measures “root tangent length” of spur gears and helical gears.
  • Determination of the root tangent length: refer to “Quick Guide to Precision Measuring
    Instruments”.
  • Equipped with Ratchet Stop for constant measuring force.
  • Supplied with a setting standard (except for 0-25mm/0-1” measuring range).
