Self-centering dial bore gage
Marameter 844 N
Art. no. 4474002
Self-centering dial bore gage Marameter 844 N
Measuring range mm 100 - 250 mm mm
Design: Standard, moveable anvil carbide-tipped
Package contains: measuring holder, measuring head, anvil spindle, wooden case, excludes indicator
- Measuring head consists of a carbide-tipped, movable measuring pin and an opposing interchangeable stationary counter probe with hardened steel 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
- High wear resistance due to carbide tipped moveable measuring pin
- 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
- Measuring head, measuring instrument holder, depth extensions, right-angle attachments, and depth stops form a comprehensive modular system
- Invar steel makes the inner measuring device insensitive to temperature influences. Body heat from the user or a rise in ambient temperature in the workplace have virtually no influence on measuring results
