• These ABSOLUTE Digimatic bore gages are exclusively designed for inside diameter measurement.
• Up to four extension rods (250mm or 500mm) can be used for measuring at the bottom of a hole 2m deep.
• ABS (ABSOLUTE) type bore gages are not subject to overspeed error.
• The display and grip can be rotated up to 320 degrees and the display can be inclined up to 90 degrees, so that it is easily readable from any direction.
• The minimum value holding function provides easy measurement of hole diameter.
• Setting the Bore Gage to a master value using a gauge block set allows quick and accurate setting.
• A Bore Gage Checker and a range of Setting Rings are available to aid in accurately setting a gage before making a measurement. (For details, refer to pages C-46 and C-47.)

* Indicators equipped with rubber bellows, such as water-proof types, cannot be used.

Contact Points

• Longer plunger stroke with no affect on accuracy.
• Carbide is used for the contact point ensuring high durability and wear resistance.
• This model reduces the  influence  of heat  from the operator’s hand by 50% by increasing the grip size and making the grip hollow-structured, thereby retaining high-accuracy measurement.
• Alternative indicators may be used in place of those recommended*.
  * Some indicators and protection covers cannot be used with these bore gages. Contact a Mitutoyo sales office if considering the use of dial or digimatic indicators other than the recommended  models.

• Optional extension rods can be attached for measuring deep holes. (For details, refer to page C-45.)
• A Bore Gage Checker and a range of Setting Rings are available to aid in accurately setting a gage before making a measurement. (For details, refer to pages C-46 and C-47).

* Indicators equipped with rubber bellows, such as water- proof types, cannot be used.

• Wide range of inside diameter measurements possible by combining one or more interchangeable rods.
• Each interchangeable rod is marked with its measuring range.
• For models supplied with more than one interchangeable rod, the full measuring range is achieved by combining spacing collars with the rods.
• Both micrometer head and rods are satinchrome finished throughout.
• The sleeve is rotated to adjust the index line position when setting to a length standard.
• Setting ring (nominal size below 300mm), CERA Inside Micro Checker, and Gauge Block accessory set are provided as a reference gage for datum adjustment (refer to page C-47, C-26, and E-17 – E20 for details).
