LDAR Series
LDAR gages feature a lightweight tubular steel frame with a reed pantograph movement. The pantograph movement utilizes parallel springs to transfer motion and is well suited to production applications as dust, dirt or coolant cannot harm or jam the mechanism.

LDAR Series Features:
- Standard with partl# 2DM125-05 .0005" graduation dial indicator
- Movement is enclosed in lightweight steel tubular frame eliminating possibility of damage
- Three point rest system offers .625" frame clearance
- 3" of depth adjustment
