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.

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.

With SPC Data Output and Zigbee Connection—Wirelessly send measurements to an SPC receiver (sold separately) to store, analyze, and manage data on your computer.

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.

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.

McMaster-Carr Approved—The performance of brand-name calipers without the cost.

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.

Carbon Fiber Body—Despite their large size, these calipers are light enough to comfortably carry around the job.
