Mitutoyo dial indicators are always up-to-date in their construction thanks to the manufacturer's constant innovations. Still, when you get right down to it, the dial indicator serves the same function it did 50 years ago. The following Mitutoyo models can be recommended and will fit perfectly in the high-end shop environment as well as the basement hobby room. These Group 2 dial indicators have bezels approximately 2-1/4" in diameter. They come with lug backs but many other types of backs can be ordered on page 219. The mounting stem is 3/8" in diameter and they can use any 4-48 thread contact point. A wide variety of contact point shapes, sizes and materials are shown on page 133. These indicators all have an excellent accuracy of ±.0001" over the first .025" of their range. Accuracy changes slightly with extended ranges (more revolutions) but remains well within accepted standards for these kinds of gages. We list the overall total accuracy on the chart below. The one-piece plastic bezel and crystal assembly is very easy to replace if/when the crystal becomes scratched or damaged. No special tools are required and you can find a list of replacement parts on page 72. You may order any indicator online by clicking its linked model number below. |
