Product Overview

Mitutoyo’s 551-331-10 ABSOLUTE Digimatic Caliper features robust carbide-tipped jaws for improved durability and wear resistance. It offers fast, slip-free measurements thanks to its ABS digital electromagnetic encoder system, which retains its zero reference even after power-off. With IP67-rated dust and water protection, this caliper stands up well in harsh machining environments. The nib-style lower jaws with rounded faces provide superior accuracy for measuring inside diameters, while the standard upper jaws cover outside measurements—including depth and step readings.
