    • The well thought-out design and the extremely accurate, precise and robust construction of our Precision Dial Gauges series offer reliability, durability and a long working life.
    • Calibrations of all our Dial gauges are traceable to national and international standards.
    • The final quality control for the whole series includes visual inspection as well as mechanical function’s tests.
    • To eliminate lateral play and resultant errors each measuring spindle is carefully matched to its stem. The accepted lateral play is standardized.
    • The bezel together with the outer dial can be rotated by 360° to set zero in any position.
    • The zero position is factory-set at 12 o’clock, and a minimum of 0,1mm pre-travel from spindle end stop is realized.
    • Adjustable tolerance markers to set tolerance limits.
    • Standard contact point with dia. 3,175mm steel ball and M 2,5 thread. A range of special contact points is optionally available.
    • Standard stem of dia. 8mm h6.
    • Materials and components are selected specifically to ensure a long working life and a premium-quality.

For many years, Käfer employees are working for the development of standards in the national standards committees (DIN, VDE). At regular intervals, we train young people in occupations like mechanics.
