This page is designed to help you find equivalents to miniature dial indicators which you might own or want to replace. It will show the new models when others have become obsolete. It can also help you find better quality equivalents or—vice versa—cheaper alternatives.
Miniature indicators are often refered to as AGD Group 0 and they have bezel diameters of about 1.25" (more or less).
We have taken the major parameters into account: the range, the graduations, the dial diameter and the stem diameter. On metric models, the stem diameter is 8 mm and on inch models the stem diameter is 3/8" unless otherwise noted. Many miniature models with different stem diameters will take non-standard contact points. Refer to the notes below.
Some indicators ship with a lug back, others have flat backs and lug backs need to be ordered separately. There will of course be some variation from one manufacturer to another. For a detailed comparison of manufacturers and brand names, refer to page 14.
Where they're made:
Many manufacturers have discontinued this size dial indicator. Discontinued models are no longer included in this listing.This page does not pretend to be exhaustive or complete. We have focused on some of the better-known and more readily available indicators in the U.S. market. Items with links will take you to pages with further details.
Starrett 80-114J is an example of the miniature Group 0 dial indicator. The stem diameter and contact point thread are non-standard.
