Bore gauge MaraMeter 844 N 18-50mm

Dial bore gauge MaraMeter 844 N manufactured by Mahr with range 18-50, measures deep holes in the range of 18-50 mm at two points.

• 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

All  dial bore gauges MaraMeter 844 N pass metrological control in an accredited ISO 17025 metrological laboratory. Warranty for bore gauges -12 months.
