Starrett Electronic Plunger-Style Variance Indicators
View measurements on an easy-to-read LCD. A spring-loaded plunger retracts and extends to measure objects. These indicators have a zero-set button that lets you start measuring at any point. Rotate the dial face for viewing at multiple angles. SPC data output allows for connection to a computer or data processor.
Indicators with go/no-go operation indicate when measurements fall outside your set tolerance.
Indicators with zero-position memory, also known as absolute (ABS) positioning, retain the measuring position when the indicator is off.
USB data cable (sold separately) connects indicators with SPC data output directly to your PC.

Starrett Electronic Depth Gauges
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.
Base extensions (sold separately) increase the base width of your depth gauge to measure large-diameter holes.

Micrometers with Calibration Certificate
These micrometers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. All are IP67 rated for protection from dust and temporary water submersion. Zero-position memory, also known as absolute (ABS) positioning, retains the measuring position when the micrometer is turned off. A zero-set button allows you to start measuring at any point.
Each 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 has stopped tightening, the thimble will continue turning with resistance.

Starrett Electronic Outside Micrometers
All micrometers have a friction thimble with a constant-force mechanism, which stops the spindle from tightening once it contacts the surface of the measured object. This ensures repeatable measurements and prevents over-tightening. Once the spindle has stopped tightening, the thimble will continue turning with resistance.
Zero-position memory, also known as absolute (ABS) positioning, retains the measuring position when the micrometer is turned off. A zero-set button allows you to start measuring at any point.

Starrett Electronic Pistol-Grip Bore Gauge Sets
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.

Horizontal Benchtop Optical Comparators
Measure and inspect precise features by projecting a magnified shadow or image of your part onto a screen. These optical comparators work similarly to overhead projectors, but with fixed magnification to preserve proportions. Because of how easy they are to set up and use, they’re a staple in most machine shops. From o-rings to castings, they work to inspect parts with simple or complex geometries. They shine light from the side, so unlike vertical comparators, your part can be held from underneath for stability. Unlike traditional optical comparators, these comparators are compact to fit easily on a benchtop.
To use these comparators, choose profile or surface lighting. Profile lighting creates a shadow of your part, which you can use to plot points for precise measurements. To plot each point, move the stage the parts rests on until the point lines up with the crosshair on the projector screen. For precision, the stage moves in increments thinner than a sheet of paper. Surface lighting makes these comparators work like an illuminated magnifier, blanketing the part with even light to reveal scratches, dents, and other surface flaws.
These comparators come with a variety of features to streamline your inspection process. For a quick way to compare manufactured parts to designs, set desired dimension and tolerance limits. You can also create a program that guides anyone using the comparator on what steps to follow, so each part is inspected the same way. To save everything for later, print the data or export it as a spreadsheet or text file to a computer with a USB or RS-232 connection.
Changing the magnification is as easy as twisting the current lens until it pops out and twisting in a new lens (sold separately).
Optical comparators with edge detection increase accuracy and efficiency by reducing human error. No need to identify each edge yourself with the crosshair—these comparators register whether they are passing over your object's shadow or a gap, such as a hole or cutout.
Rotary vises (sold separately) give you a secure way to hold up and rotate objects.
Cabinets (sold separately) can serve as a stand for your comparator and as storage for lenses and other accessories.
