Mitutoyo 2050S metric dial indicator
Guaranteed Genuine Mitutoyo


Mitutoyo is an obvious choice when selecting metric dial indicators. They are reliable and affordable. Spare parts are also available should you ever need to make a minor repair (new contact points, new bezel and crystal, new locking screw, for example.)

The bezel diameter is about 2-1/4" (57 mm). The mounting stem is a regulation 8 mm in diameter on white dial models. A yellow dial will indicate that it has a 3/8" diameter stem. It comes complete with lug back for secure fastening to magnetic stands, granite stands and fixtures.

It features a new Mitutoyo innovation: two dovetails are integral with the outside of the metal case to which you can easily clamp any dovetail accessory, including the bezel clamp (included). If you want, the indicator can now be mounted to a stand or fixture directly from the case rather than the back or the stem. Tolerance markers are included with this model.

Made in Japan. When buying from an authorized Mitutoyo distributor, you are guaranteed to get a genuine Mitutoyo indicator, not one of the Chinese rip-offs which have recently flooded the markets at not-surprisingly cheap prices. If buying from Amazon look for the wording "ships from and sold by Amazon.com"

Idea: add a magnetic base stand to hold your dial indicator. An ideal combination for the shop and automotive work.

Do you need to go deeper than 1"? Use contact point extensions with your dial indicator. These will not increase the amount of travel, but they will extend the reach. See page 133.

Some hints on maintenance, inspection and repair

Do not oil the spindle. If it gets dirty, wipe it with a cloth and some alcohol. Oil attracts more dirt which can hinder the free movement of the spindle.

Don't unscrew the top screw. The gears will disengage.

The indicator takes M2.5 thread contact points which you can change as needed. Additional points in all sizes and shapes are available on page 133.

When the plastic crystal is dirty, spray some Windex on a paper towel and then wipe the crystal clean.

Check the indicator periodically to make sure it's still accurate. Use gage blocks for this purpose. (see index for calibration instructions).

The indicator's serial number is printed on the dial face along with a scan code.

You'll risk losing the 1-year warranty if you mess with the indicator. Send it to Long Island Indicator for repair if there's a problem. See page 30 for repair details.
