1,000 mm Calipers | McMaster-Carr

The most precise and versatile calipers. Their LCD display gives instant measurements down to 0.0005”—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.

Our calipers come with a signed certificate of inspection, so you can trust your measurements are accurate every time. Their precision-ground jaws glide up and down the body for a silky-smooth feel.

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.

Starrett—Starrett calipers come packaged in their iconic wood or red plastic case, so you'll be able to spot them on the busiest of bench tops.

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.

Precision-Adjust Digital Calipers

Position the jaws exactly where you need them. The fine-adjustment wheel opens and closes the jaws in small, precise increments for extra control while measuring.

Precision-Adjust Vernier Calipers

Move the jaws exactly where you need them. The fine-adjustment wheel opens and closes the jaws in small, precise increments for extra control while measuring.

These classic calipers use a sliding vernier scale. Just add the measurement from the main scale to the measurement on the vernier scale to get accurate readings as small as 0.001". Made completely out of metal, they won't break when dropped or short-circuit when wet. They're battery-free, so they're always ready to use.

Coolant-Resistant Digital Calipers

Measure parts inside CNC machines and other places coated with coolant and cutting oil. The display and battery cover are tightly sealed, so spraying and dripping fluids won't seep in.
