Description Specification

MaraMeter 844 N Self-centring dial bore gage

MaraMeter 844 N Self-centring dial bore gage

  • Measuring head consists of a carbide tipped moving anvil and an interchangeable stationary anvil with a hardened steel 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 because the shank and transfer rod are made of heat resistant Invar steel

  • Highly resistant to wear and tear because of carbide tipped moving anvil

  • Constant measuring force due to built-in spring, eliminating user influence

  • Universally applicable and extremely versatile

    - Each instrument spans a broad measuring range

    - Quick and easy to adjust to any size (within its range)

  • Extensive modular system is composed of measuring head, holder, extensions, right angle attachments and depth stops

  • Invar steel has a particularly low expansion coefficient

    - instrument totally insensitive to any kind of heat (including user body heat and increased ambient temperature)

  • Measuring head consists of a carbide-tipped, movable measuring pin and an opposing interchangeable stationary measuring anvil with carbide ball

  • Stationary measuring pin can pivot by 180°. This results in a very long return travel path of up to 40% of the bore to be measured

  • Movements of the measuring pin are transmitted to the indicating instrument via the ring segment

  • The broad centering bridge ensures automatic centering in the bore

  • Insensitive to temperature due to both the shaft and the transfer rod being made from Invar steel

  • Carbide-tipped measuring contacts for high wear resistance

  • Constant measuring force thanks to inbuilt measuring force spring. Measuring results are therefore independent of personal sense of touch

  • Universally applicable. Every instrument spans a broad measuring range. Within this range it is quick and easy to adjust to any size

  • Invar steel makes the inner measuring device insensitive to temperature influences of any kind. Body heat from the user or a rise in ambient temperature in the workplace have virtually no influence on measuring results
