Group 3 Dial Indicator Equivalent Models
indicators with large dials

Group 3 dial indicators have large dials about 2.75" in diameter. The exact diameter can vary slightly from manufacturer to manufacturer. It is harder to make a large face indicator which remains accurate. You should only use these if there is a specific reason. Perhaps your dials are at some distance from the viewer and a larger face is need so that it can be seen. Otherwise, stick to the Group 2 dial indicators which offer the same specifications but are less troublesome and will cost you less as well. Refer to page 202 for Group 2 indicator comparisons.
