Mitutoyo 551-226-10 ABSOLUTE Digimatic Caliper 0-30 in / 0-750mm with Nib Style and Standard Jaws

The Mitutoyo 551-226-10 ABSOLUTE Digimatic Caliper is a large-range digital caliper offering a full 0–30 inch / 0–750mm measurement range with a resolution of 0.0005" / 0.01mm and an accuracy of ±0.0025". Built from durable hardened stainless steel, this Series 551 caliper is engineered for demanding industrial and metrology applications where long-range precision measurement is required.

This model features both standard upper jaws for outside diameter (OD) measurement and rounded nib-style lower jaws for inside diameter (ID) measurement. The nib-style jaws are ideally suited for gripping round and spherical surfaces, providing accurate and repeatable ID readings.

Key Features:

• ABSOLUTE electrostatic capacitance linear encoder — retains the origin point after power-off, eliminating the need for repeated zero-setting and preventing overspeed errors
• Dual jaw design — standard jaws for OD measurement; rounded nib-style jaws for accurate ID measurement of curved and spherical surfaces
• SPC data output — built-in Statistical Process Control (SPC) output for connecting to a Mitutoyo miniprocessor, computer, or data recorder via SPC cable (sold separately)
• Large LCD display — clear, parallax-free readout with inch/mm conversion capability
• Function buttons — Origin-set, Zero-setting, and Data Output controls are easily accessible
• Low voltage and counting error alarms — alerts operator to battery or encoder issues
• Powered by a single SR44 silver oxide battery — with an approximate lifespan of 3.5 years under normal use
• Supplied in a fitted wooden case — standard packaging for calipers 18" / 450mm and larger

The 551-226-10 is part of Mitutoyo's trusted Series 551 ABSOLUTE Digimatic caliper line, designed for professionals who require reliable large-format measurement capability with digital accuracy and SPC integration. Note: this model is not IP67 rated.
