Marameter 844 KC

Self-centering dial bore gage

FEATURES

• Measuring head made in
harden steel, DLC coated
• Constant measuring force as a
result of built-in spring, eliminating Application:
user influence Standard model with DLC-coated surface
• Extensive modular system is
composed of measuring head, • For indicating measurment of diameter and testing for
transfer needle, holder, depth roundness and conicity of bores
extension, right angle attach- • Especially suitable for testing batches
ments and setting rings • Determine the reversal point per rocking in the bore

• Benefits of DLC-Coating
- Explanation DLC = Diamond
Like Carbon TECHNICAL DATA
