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
