MAHR MaraMeter 840 FS Indicating snap gage

Rugged, forged steel frame with heat insulators

Both spindles are made of hardened stainless steel and mounted in long guideways

Carbide tipped measuring faces slightly chamfered at the front to facilitate positioning

Projects over width of frame for measurement of narrow registers or when measuring directly at shoulders

Adjustable centering stop for surface centering

Straight transfer of spindle movement to indicator; ensures the weight of the gage rests on the anvil spindle

Direct indication and evaluation of measurement results

Constant measuring force as a result of built-in spring, eliminating user influence
