MaraMeter 844 NH
Self-Centering Dial Bore Gage
FEATURES
• Measuring head consists of a
carbide tipped moving anvil and
an interchangeable stationary
anvil with a carbide ball
• Transmission lever system
transfers movement of movable
anvil to indicating instrument
• The broad centering bridge
ensures automatic centering in
the bore
• Resistant to temperature bacause Application:
the shank and transfer rod are
made of heat resistant Invar steel
• Highly resistant to wear and tear
due to the carbide tipped • Measuring the diameter, roundness and conical form of a bore as well as
moving anvil the distances of parallel plane surfaces
• Constant measuring force
because of built-in spring,
eliminating user influence TECHNICAL DATA
