Precisely measure shallow holes, slots, and recesses without any fine adjustments. Simply press these gauges against the bottom surface and push a button to measure. The LCD display makes measurements easy to read. Shaped to fit your palm, these gauges are also comfortable to hold and position. Store measurements on the gauge or wirelessly send them to a computer or data processor up to 30 ft. away using the built-in transmitter. With SPC data output, you can remotely analyze data and monitor measurements in real time.

A zero-set button lets you start measuring at any point. With zero-position memory, also known as absolute (ABS) positioning, these gauges retain their measuring position when the scale is off. To save battery life, they turn off after 20 minutes of inactivity.

Take height measurements and set the attached scriber at a specific height for repeat marking. These gauges have zero-position memory, also known as absolute (ABS) positioning, which retains the measuring position when the gauge is turned off. A zero-set button lets you start measuring at any point.

These gauges come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. They have a scriber that can be set at a specific height for repeat marking. All have zero-position memory, also known as absolute (ABS) positioning, which retains the measuring position when the gauge is turned off. A zero-set button lets you start measuring at any point.

An LCD display helps you read depth measurements of drilled holes and machined slots. These gauges are often used for quality control in manufacturing plants and laboratories. Store data internally or use the SPC data output to connect to a computer or data processor. This allows you to analyze data and monitor measurements in real time. The zero-set button lets you start measuring at any point. With zero-position memory, also known as absolute (ABS) positioning, these gauges retain their measuring position when the scale is off. To save battery life, they turn off after 30 minutes of inactivity.

Set includes a caliper, a micrometer, and a case. The micrometer has a friction thimble with a constant-force mechanism, so that once the spindle contacts the surface of the measured object, it will stop tightening. This ensures repeatable measurements and prevents over-tightening. Once the spindle stops tightening, the thimble will continue turning with resistance.

Check the diameter of holes with the pull of a trigger. These Starrett sets have everything you need for one-handed measurements—a pistol-grip gauge, heads for varying diameters, and setting rings. Thanks to its pistol grip, you can reach the gauge into awkward spots, such as those overhead. The pistol grip also gives you precise control using just your fingertips instead of your whole hand. Unlike dial bore gauges, you can measure right away, no baseline measurement required. You can even set upper and lower tolerances for quick go/no-go tests. The LCD display has lights and arrows to show if the hole falls within your set tolerance. Rotate the display to read results at the angle you need.

Since the gauge has three contact points, it’s more accurate than a typical bore gauge with two contact points. The probe centers itself, so it’s easier to detect issues with roundness, a common check in quality control tests. To stay accurate, the gauge has alarms to warn you about problems that could skew readings, such as a low battery, a contaminated probe, and test setting errors. Use the included setting rings to calibrate your gauge.

With a zero-set button, you can start measuring at any point. Zero-position memory, also known as absolute (ABS) positioning, retains the measuring position when the gauge is off. Connect the gauge to your computer, smartphone, or other device via Bluetooth or the SPC data output to monitor and analyze data in real time.
