Internal Dial Caliper
Internal dial calipers are suited for measuring bores,internal groove,and other hard-to-reach inside dimension.The data of Max. and Min. can be remembered ,or the displaying data can be held,the tolerance can be set.
Internal dial caliper Type-A
Electronic system
• Inside dial caliper are suited for measuring bores,internal
groove,and other hard-to-reach inside dimension.
• Dial rotates ±170° for use at versions angles.
• Display data is origin data of absolute measurement
after changing battery.
• Digital display and analog display on LCD automatic switch over.
• Analog display range: ±20 graduation.
• Digital resolution:
0.005mm(Metric);0.0002"(Inch).
Analog resolution:
0.01mm;0.02mm;0.05mm(Metric); 0.0005";0.001";0.002"(Inch).
