Features

Application  
Product Features  
  • Measuring head consists of a carbide-tipped moving anvil and an interchangeable stationary anvil which has a carbide ball.
  • Transmission lever system transfers movement of the movable anvil to indicating instrument.
  • The broad centering bridge ensures automatic centering in the bore.
  • Insensitive to temperature due to both the shank and transfer rod being made from heat resistant Invar steel.
  • Highly resistant to wear and tear due to the carbide tipped moving anvil.
  • Constant measuring force due to built-in spring thus eliminating user influence.
  • Universally applicable and extremely versatile as every instrument spans a broad measuring range, within this range it is quick and easy to adjust to any size.
  • Invar steel has a particularly low expansion coefficient and thus makes the instrument totally insensitive to any kind of heat.
  • Body heat from the user, increases in ambient temperature have no influence on the measuring results.
  • The graph on the right compares the Invar steel version to a standard type.
  • Both Gauges were hand-held and thus influenced by body heat.
  • The deviation when using Invar steel is negligible.
