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.

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.

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.
