Dial indicator model 2776S (formerly model 2776F) with a 1" range, reading in .0005" is, in our opinion, the best indicator for your money. It's consistently reliable, accurate and repairable.

This indicator has a permissible error of .0005" over its first 2-1/2 revolutions and ±.002" over its one inch range. The indicators we've seen astonishingly keep this tolerance to .0005" over the entire range.

The bezel diameter is about 2-1/4". 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. Two tolerance markers are also included which you can attach to the cover. Made in Japan.

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.

 

 

 

Maintenance, inspection and repair: some hints

 

  • Don't oil the spindle. If it gets dirty, wipe it with a cloth and some alcohol.
  • Don't unscrew the top screw. The gears will disengage.
  • The indicator takes 4-48 thread contact points which you can change as needed.
  • 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 calibration instructions).
  • 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.

 

 

 

Replacing the bezel and crystal

 

The bezel and crystal are one unit, made of plastic (unfortunately!). It is held in place with a rubber o-ring. Pry the bezel loose with a broad bladed screw driver. Press the new bezel down, squarely, so the rubber o-ring snaps in place. You should be able to rotate the bezel freely. If there's too much friction, apply a bit of vaseline to the o-ring. New bezels are available from our spare parts list.
