* Except for universal type dial test indicator (513-304G).

• Stylus length affects the scale factor of an indicator. The styli provided as standard give a scale factor of unity.

• Bezel is sealed with on O-ring to keep out water and oil.

SPECIFICATIONS

DIMENSIONS

There are two types of Mitutoyo Dial Test Indicator: The non-clutch type (without a clutch lever) and the clutch type (with a two-position clutch lever)

In the non-clutch type, although the contact point may move either in the upward or downward direction, the pointer always rotates clockwise. In the clutch type, if the clutch lever is set in one position the contact point moves in the upward direction and the pointer rotates clockwise. Conversely, if the lever is set in the other position the contact point moves in the downward direction and the pointer rotates counterclockwise.

Set Configuration: Metric

Set Configuration: Inch

• Universal application to all directions. (Not only the direction of the measuring point, but also the direction of measurement itself can be adjusted 360 degrees without moving the indicator.)

• Specially designed for easy viewing of dial.

The dial face obliquely faces upward, allowing users to read the graduations from the user’s side. It is convenient when probing on the side of a large workpiece and the workbench is high.

Using the universal holder allows easy hole centering. The dial face always faces upward when the indicator is rotated, which makes reading easy.

• Designed to probe surfaces that cannot be reached with a normal dial gauge. Useful both for alignment and for measurement purposes.
• Mitutoyo’s proprietary new design permits smooth pointer operation.
• Strong frame provides excellent rigidity and durability.
• Non-magnetic pointer and contact point permit reliable operation even in magnetic environments.
• Clear and concise wide dial face allows excellent visibility.
• The surface of the crystal is hard-coated for excellent scratch resistance.
• Flat crystal makes graduations easy to read. Moreover, the O-ring sealing method used for the bezel prevents water or oil penetration. (Note that this type is NOT waterproof.)
• Six types are available: horizontal, horizontal (20° tilted face) vertical, parallel, universal, and pocket, allowing users to select the model most suited to their needs. · Horizontal: Standard · Horizontal (20° Tilted Face): Dial face inclined 20°, compared with the vertical type, allows easy reading. · Vertical: Best suited for centering holes under the spindle of a machine tool. · Parallel: The scale can be read from the front, with the stylus pivoting in a plane parallel to that of the dial face. · Universal: The direction of the probe movement can be freely changed. · Pocket: Compact type.
  
• Dial test indicators with a ruby contact point are available in the horizontal (standard) type.
• Benefits of ruby contact points: · Several times more resistant to wear than carbide. · Can be used on electrical discharge machines without special precautions.

Feature icons

• Back plunger type dial gauges are suitable for mounting onto leveling machine tool tables or inspection jigs, and for use in situations where standard dial gauges are difficult to read.
• Model 1960T and 1961T, which uses Mitutoyo’s proprietary shock-proofing mechanism, has excellent durability and shock resistance.

DIMENSIONS

Note 1:
Contact point (standard accessory) for all products in this page has a role as a top dead point stopper. For this reason, if you need to install an optional contact point with an outside diameter smaller than 7mm, use a washer (with outside diameter of at least 7mm, inside diameter of 3mm, and thickness of approx. 0.5mm) placed between the contact point and the spindle.
Note 2:
Dimensions of the inch (ANSI/AGD Type) dial indicator partly differ from those of the metric (ISO/JIS Type) indicator.
Note 3:
Inch (ANSI/AGD Type) dial indicators are provided with a stem of 3/8″ dia. and #4-48UNF thread mount for the contact point.
