Features:

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