All gauges have zero-position memory, also known as absolute (ABS) positioning, which retains the measuring position when the gauge is turned off.

Connect multiple extension rods to measure depths up to 22". Measurements are easy to read and displayed on an LCD screen.

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

Reach deep into small holes and slots for precise depth measurements.

Check measurements at a glance.

Measure the depth of holes, slots, shoulders, and projections by changing out the steel extension rods supplied in 1" incremental lengths.

Use extension rods in 1" incremental lengths to measure the depth of holes, slots, shoulders, and projections.

IP54 rated for limited protection from dust and splashing water.

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 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.

Often used in machine shops, these indicators are rated IP65 for protection from dust, spraying water, and coolant.

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.

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

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.

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

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.

Read measurements on an LCD. These Mitutoyo indicators have a spring-loaded plunger that retracts and extends to measure objects.

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

A slim design fits in tight spots. These indicators have a spring-loaded plunger that retracts and extends to measure objects.

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.

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

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

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

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

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

Read measurements from up to 4 ft. away.

Position the arm by adjusting joints at the top, middle, and bottom. The magnetic base provides a solid mount on metal surfaces.

Sets include attachments for indicator mounting.

Measure larger ranges than with our other lever-style indicators.

Sets include additional contact points and mounting accessories.

Rulers are narrow, flexible and just 6" long to measure in tight, slightly curved spaces.
