In various contexts of science, technology, and manufacturing (such as machining, fabricating, and additive manufacturing), an indicator is any of various instruments used to accurately measure small distances and angles, and amplify them to make them more obvious. A test indicator measures the deflection of the arm, the probe does not retract but swings in an arc around its hinge point. 1-1/2" diameter dial face rotates a full 360°, Meets or exceeds DIN/ISO Standards. Typically a DTI comes with only a few tips, such as a small-ball tip and a large-ball tip.

Many indicators have a mounting lug with a hole for a bolt as part of the back plate. Changing the tip of a DTI is not as simple an affair as changing the tip of a drop indicator, because the tip, being a lever, has its length precisely matched to the clockwork inside the indicator, so that the length of the arc of its extremity's movement has a known ratio to the gears that drive the dial's needle. Other types of indicator include mechanical devices with cantilevered pointers and electronic devices with digital displays. A dial test indicator, also known as a lever arm test indicator or finger indicator, has a smaller measuring range than a standard dial indicator. This test indicator includes a wireless remote display that allows you to mount the indicator in a position where it would be hard to read a dial, and then display the indicator's readings on the remote display up to 30' away. The QuadraTest features four measuring modes (Min, Max, TIR and direct), with an RS-232 interface that is water, oil and coolant resistant to IP65 compliancy WITH or WITHOUT the interface cable installed! Mitutoyo offers a wide variety of indicators to fit a wide range of uses. Modern dial test indicators are usually mounted using either an integrated stem (on the right of the image) or by a special clamp that grabs a dovetail on the indicator body.
