Mitutoyo 552-161-10 Electronic Caliper 24 in IP66

Product Description

The MITUTOYO 552-161-10 is a large-range digital electronic caliper from the 552 Digimatic Carbon Fiber series, designed for precise outside and inside diameter measurements in demanding shop environments. Built with a carbon fiber reinforced plastic beam and jaws, the caliper offers a 24-inch maximum range with a resolution of 0.0005 inches and an accuracy of 0.0025 inches. The IP66 rating seals the instrument against coolant splash and dust ingress, making it suitable for active machine shop use. Machinists, tool-and-die technicians, and metrology professionals use this caliper for high-precision dimensional inspection where corrosion resistance and lightweight handling are priorities.

The 552-161-10 is suited for both production floor and inspection bench applications requiring measurements up to 24 inches. The 7.9-inch nib-style jaws support outside diameter and inside diameter measurement tasks on large workpieces, castings, and fabricated components. The data output port allows integration with SPC software or Mitutoyo data collection systems for statistical process control workflows. A included case protects the instrument during storage and transport. This caliper is intended for use by skilled trades and metrology personnel in industrial, manufacturing, and tool shop environments.

Installation Notes

No permanent installation is required. Prior to first use, verify battery is seated correctly and zero the caliper at closed-jaw position following the manufacturer calibration procedure. Keep the sliding jaw track clean and free of chips or coolant residue to maintain measurement accuracy. This instrument is not factory-calibrated as shipped; calibration to a traceable standard should be performed by qualified metrology personnel per applicable quality system requirements before use in a controlled inspection process.
