Measure diameters, angles, and other complex geometries—like an optical comparator—but without all the training. These gauges have an easy-to-use touch screen that guides you through taking measurements step-by-step. Extremely precise, they measure in the smallest increments of any height gauge in our offering, and they’re also our most accurate. Use them in machining and toolmaking to mark material before cutting it. To fly through big batches of work, program up to 50 types of repeated measurements.

From calibration reminders to calculation error alarms, these gauges have functions to make sure they give you accurate and consistent readings. Upon startup, they walk you through a scale check to detect traces of contamination that would cause errors. The air bearing system helps the slider glide smoothly up and down yet holds its spot steady when it’s time to measure. Rotate the screen to read it at the angle you need. Zero-position memory, also known as absolute (ABS) positioning, retains the measuring position even when the gauge is turned off.

With up to two months of storage to record actions and measurements, these gauges create an archive you can look through and identify trends. Connect them via Bluetooth to your phone, tablet, or other devices to remotely monitor and analyze data in real time. Otherwise, use the SPC data output to connect to a computer or data processor. To send data right into programs such as Excel, use a USB cord or RS-232 cable (both not included).

Measure height more precisely than standard height gauges. These gauges are often used to mark material before cutting it for machining and toolmaking. They have two vertical scales—a main scale and a sliding vernier scale. The vernier scale splits the graduation marks on the main scale into smaller increments for a more accurate reading. Set your initial height, then fine-tune with the adjustment screw.

Read measurements on a dial or using the two mechanical analog counters (one counts up; the other counts down). Use the hand wheel to adjust height up and down the column, and set the attached scriber at a specific height for repeat marking.

Set the standard for your height gauges. These calibrators combine gauge blocks—a true source of measurement—and a micrometer head for refining the gauge block measurement even more. Since they’re so precise at checking that height gauges take accurate readings, they’re often used in metrology labs. Rather than stacking gauge blocks, line up your height gauge against the built-in blocks. They’re staggered to expose both the top and bottom faces, which lets you check height from either bottom up or top down. To fine-tune the entire stack up and down, twist the micrometer head. No need to calculate anything, since the counter keeps track of adjustments and total height shows on the display.

These calibrators include a zero-setting block to make sure your measurements start from an exact reference point. They also have zero-position memory to retain the measuring position even when turned off. This is also known as absolute (ABS) positioning. To warn you about issues that could skew readings, such as low battery and calculation errors, they show alerts on the display. An SPC data output lets you connect them to a computer or data processor to analyze data and monitor measurements in real time.

Riser blocks (sold separately) extend the height range. Precisely manufactured, they have tolerances as tight as our typical gauge blocks of similar sizes. Snap them seamlessly to the bottom of your calibrator with the pins. To add the riser height to your total measurement, input the height into the calibrator’s counter.

Ensure parts are perfectly straight and square—these gauges detect surface deviations so small the human eye can’t see them. As you slide the lever on these gauges up and down, a dial test indicator moves along the vertical surface of your workpiece, measuring how straight and square it is. Checking for slight angles on machined parts or frames verifies they will align properly and function correctly. You can adjust the squareness of the gauges to fine-tune for differences in temperature and humidity and to maintain precision over years of use. Measure an object for height with the scale along the side of the gauge. The housing is cast iron, so the gauges are stable and stand up to frequent use.
