- 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).
