Description
Self-centring dial bore gage Marameter 844 NH
Features:
- Measuring head consists of a carbide-tipped, movable measuring pin and an opposing interchangeable stationary counter 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
- 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 of any kind. Body heat from the user or a rise in ambient temperature in the workplace have virtually no influence on measuring results
