Calipers for Pipe and Tubing

The rounded jaw hugs the inside of pipe and tubing, so you can accurately measure their wall thickness.

With an LCD display, these calipers give instant measurements—no need to count graduations. Swap between inch and metric or set the position to zero, all with the press of a button. You don't need to reset the zero point since they retain their position when turned off, also known as absolute (ABS) positioning.

Mitutoyo—The go-to for machinists and engineers. Every part of these calipers is made within Mitutoyo's automated system and tested in-house in Japan. Their jaws are laser cut to exact dimensions for the most reliable measurements.

With SPC Data Output—Send measurements to a computer or data processor to store, analyze, and manage data. You'll need a data cable or SPC wireless transmitter and receiver.

Calibration Certificate—Choose these calipers when precision measurements are required for quality control or by regulation. The certificate is traceable to NIST, so you can be confident your measurements are correct and consistent.

Electronic Thickness Gauges for Pipe and Tubing with Calibration Certificate


Model Number 547-561S	Model Number 209-954

These gauges come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. They measure the wall thickness of pipe, tubing, and other curved surfaces. Zero-position memory, also known as absolute (ABS) positioning, retains the measuring position when the gauge is turned off. A zero-set button lets you start measuring at any point. All have SPC data output to connect to a computer or data processor.

SPC Transmitters—SPC Wireless data transmitters allow you to transmit measurement data from the gauge to your PC without being tethered by a cable.

Digital Outside Micrometers for Pipe and Tubing

At a glance, measure the thickness of pipe and tube walls. The round anvil hugs curved surfaces, so you don't measure a gap.

With an LCD display, these micrometers give instant measurements—no need to read scales. Swap between inch and metric or set the position to zero, all with the press of a button. You don't need to reset the zero point since they retain their position when turned off, also known as absolute (ABS) positioning.

Mitutoyo—The go-to for machinists and engineers. Every part is made within a Mitutoyo automated factory and tested in-house in Japan. The spindle glides as you turn the thimble with a weighty, silky-smooth feel.

With SPC Data Output—Send measurements to a computer or data processor to store, analyze, and manage data. You'll need a data cable or SPC wireless transmitter and receiver.

Calibration Certificate—Choose these micrometers when precision measurements are required for quality control or by regulation. The certificate is traceable to NIST, so you can be confident your measurements are correct and consistent.

Ratchet-Stop Thimble—Best for consistent, repeatable measurements. The spindle stops extending the moment it reaches your part, so it won’t overtighten. Hear and feel a satisfying click that confirms you’ve applied the right amount of pressure.

Digital Outside Micrometers for Curved and Flat Surfaces

Swap between two anvils to view curved and flat surface measurements with the same screen. The straight anvil sits against flat surfaces without wiggling. The round anvil hugs curved surfaces, so you don't measure a gap.

With SPC Data Output—Send measurements to a computer or data processor to store, analyze, and manage data. You'll need a data cable or SPC wireless transmitter and receiver.

Friction Thimble—Control how tightly the spindle closes on your part without the risk of damaging it. You can keep extending the spindle in small increments once it reaches your workpiece but not enough to overtighten. The thimble will start to resist turning to let you know you’ve applied the right amount of pressure.

Outside Micrometers for Curved and Flat Surfaces

Swap between two anvils to measure curved and flat surfaces with the same micrometer. The straight anvil sits against flat surfaces without wiggling. The round anvil hugs curved surfaces, so you don't measure a gap.

To find your exact measurements, read the scales on the sleeve and thimble. These micrometers are free of electronic components that could break if dropped or short-circuit if wet. You don't have to replace any batteries, so they're always ready for the job.

Starrett—Precision machined and tested in the U.S. These Starrett micrometers come packaged in their iconic red case, so you'll be able to spot them on the busiest of bench tops.
