Features

  • Measurement of diameter, roundness and conicity of bores
  • Spring-loaded halfs of measuring probe are split via expanding pin with precision-lapped taper. This movement is transferred to indicating instrument
  • Maximum wear-resistance due to hard chromium-plated measuring faces, 4 mm and above carbide-tipped measuring faces on request
  • Constant measuring force as a result of built-in spring thus eliminating user influence
  • Highly versatile. Each gauge covers a large range. Within the respective limits, quickly and easily adjustable to any size and any type of measuring application
  • Measuring probe, holder, angle attachments and depth extensions, right-angle attachments and depth stops are part of an extensive modular system
