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.

Sets include a contact point adapter, swivel clamp, hole attachment, and mounting accessories.

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 Mitutoyo indicators have a continuous dial numbered clockwise around the face.

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

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.

Place the magnetic base on metal surfaces for a solid mount. The base has a V-grooved bottom for mounting on flat and curved surfaces and magnetic release switch for easy setups.

With adjustable magnetic pins that conform to any shape, the base on these variance indicators mounts securely to uneven surfaces.

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.

Often used where space is tight or there’s not much of a surface for mounting, the clamp on these indicators fits where a weighted or magnetic base can’t.

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

These indicators have a larger display than other Mitutoyo electronic indicators for easier reading.

Check whether measurements are in tolerance at a glance. LCD backlighting changes from green to red to indicate when measurements fall outside your set tolerance.

Stick the magnetic base onto metal surfaces for a secure hold while measuring.

Bend and flex the arm of the base to position your indicator—these holders have ball-and-socket segments that lock in place with a lever. The base is magnetic and mounts to flat and curved metal surfaces.

These indicators can display readings in fractional increments in addition to decimal increments.

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.

Sets include attachments for indicator mounting.

A slim design lets you measure in tight spots.

Measure internal surfaces that standard contact points can’t reach. These adapters transfer the up and down motion of the contact point 90° to a second contact point that moves left to right.

Operated with a quick press, these levers are a simpler alternative to pinching and manually lifting the plunger on your variance indicator.

Use these rods to extend the reach of your indicator.

Use with swivel clamps to position indicators.

Install these attachments onto Starrett magnetic-base holders for more precise control over positioning.

Securely mount indicators to metal surfaces with the magnetic base on these holders.

For more versatility than other low-profile holders, this holder has six locations for mounting indicators and accessories, including two mounting holes and four places to mount an indicator lug back with the included thumb screws.

Use a swivel clamp to attach an indicator to the positioning arm.

The base is comprised of adjustable magnetic pins which allow it to conform to any shape and grip most metal surfaces.

The pins on these bases adjust to grip a variety of contours, such as sharp, rounded, and uneven surfaces.

Commonly used on workbenches, these stands have a heavy granite base for stability. They hold indicators in place for taking accurate readings.

These holders come with a calibration certificate traceable to NIST states that the granite base has passed a test for surface accuracy. The extremely tight flatness tolerances of the granite allow for nearly frictionless workpiece movement and provide an accurate reference plane for inspection work.

Stabilize and precisely position your indicator with these weighted bases.

Adjust the flexible arm to nearly any position.

Attach the C-clamp on these holders to your milling machine head to take indicator measurements without obstructing the cutting tool.

Vise-grip locking pliers clamp these holders to most thin, flat surfaces, and the flexible arm lets you position your indicator around obstructions.

With a calibration certificate traceable to NIST that says they've passed a test for accuracy, you can trust these gauges to confirm if your object's outer diameter is within tolerance. They're also known as snap gauges because they snap onto rods, shafts, and other cylindrical objects.
