Mitutoyo 500-193-30 Digital Caliper | 12" AOS | Stainless Steel

For professionals who need to measure what others can't reach. The Mitutoyo 500-193-30 Digital Caliper extends Mitutoyo's legendary precision to a 12-inch (300mm) measuring range — the large-format solution for engineers, toolmakers, and metrology professionals who require accurate, repeatable measurements across wider workpieces and components.

Built around Mitutoyo's AOS (Absolute Origin System) encoder, the 500-193-30 retains its zero setting without battery power — a critical advantage in production environments where batteries are changed frequently. The full stainless steel body with hardened measuring faces provides exceptional rigidity and wear resistance across the extended 12-inch range, ensuring dimensional stability and consistent accuracy over years of heavy use. With resolution of 0.0005"/0.01mm and certified accuracy of ±0.001"/±0.02mm across the full 12-inch span, this caliper delivers lab-grade performance in a robust shop-floor instrument.

Capable of outside, inside, depth, and step measurements. Includes large, easy-read LCD display, inch/metric conversion, thumb-roller for smooth one-handed operation, SPC data output port, protective case, and battery. Made in Japan to ISO/JIS standards.
