功能

• Robust and precise structure.
• Titanium coating (measuring range 6 mm or more) is applied to the measuring surface.
• Since it is a three-point inner micrometer (measuring range 6 mm or more), stable measurement is possible by automatic centripetal action.
• You can measure near the bottom of the hole.
• The HT-8R to HT-300R can also be connected with an extension rod (optional) to measure deep holes.
• [Notes]
• The difference is the value when the entire surface of the measuring surface is hit.
• The maximum difference is the difference between the maximum and minimum of the instrument differences.
• D1, D2, E1 - E3 are two point expressions.
• Setting is optional. *The measuring range cannot be changed by the measuring head section other than the one supplied with the standard. (Accuracy is not guaranteed.)
