• 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 the shank and transfer rod are made of heat resistant Invar steel
  • Highly resistant to wear and tear due to the carbide tipped moving anvil
  • Constant measuring force because of 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)
