This page is designed to help you find equivalents to metric 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.
If you are looking for indicators with small bezels (about 40 mm diameter) please see page 120.
We've taken the major parameters into account: the range, the graduations, the dial diameter and the stem diameter. 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.

By clicking on a linked model number, you will be taken to a page which has further details on that particular model. We do not pretend that this listing is complete. It does not include obsolete models, generic brands, or models that are generally unavailable in the U.S.
This diagram of the dimensions of a Mitutoyo Group 2 indicator is a good representation of accepted standards. Most notably, the dial diameter is around 57 mm.

most indicators are available with flat or lug backs. We have not included all the options in this list. If an indicator is listed with a flat back, it just means that you'll have to order a lug back separately. The opposite applies to indicators with flat backs. Whenever you buy a new indicator, always specify what kind of back you would like.
there is some variation in the bezel diameter among manufacturers but they're approximately 57 to 58 mm. That's why they're grouped under the "Size 2" category.
metric indicators sold for the American market often have yellow dials. The rest of the world uses white dials for their metric models. Mitutoyo seems to use yellow when the indicator is metric reading but has AGD 4-48 contact point threads and 3/8" diameter stems. Those models have the -11 suffix.
This is the Mitutoyo co-ax revolution counter dial.
