These indicators come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy.

For comparative measurements of a part's tolerance against a reference measurement, these Starrett indicators have a balanced dial with positive values on one side and negative values on the other side.

The contact point is located on the back of this indicator, which allows the dial face to be read from above. It has a continuous dial numbered clockwise around the face for direct measurements.

Use these indicators near magnetic chucks and other equipment with a magnetic field. Sets include a contact point adapter, swivel clamp, hole attachment, and mounting accessories.

Read the dial face from above—a spring-loaded plunger on the back of these indicators retracts and extends to measure objects. These indicators have a continuous dial numbered clockwise around the face, so it’s easy to see how much a dimension increases.

For direct measurements, these indicators have a continuous dial numbered clockwise around the face.

Take direct and comparative measurements with the same indicator. The combination dial has both a continuous scale numbered clockwise around the face and a balanced scale with positive values on one side of the zero and negative values on the other side.

Jointed at the top, middle, and bottom, the arm holding these variance indicators adjusts to various angles.

Measure in almost any position—these variance indicators have an adjustable ball-and-socket arm that locks in place with a lever.

For a solid mount on metal surfaces, these indicators come with a magnetic base. They have a continuous dial numbered clockwise around the face for direct measurements. A spring-loaded plunger retracts and extends to measure objects.

Clamp these indicators onto your machine or other surface—they take up less space on your surface than indicators with a magnetic or weighted base. The plunger is on the back of the dial, so you can read the dial face from above.

Sets include attachments for indicator mounting.

Mount these indicators to a lathe tool post or a height gauge with the included attachment, also known as a universal shank.
