Mitutoyo 500-196-30 Digital Caliper
The Mitutoyo 500-196-30 is an industry-standard 0–150 mm (0–6 inch) Absolute Digimatic digital caliper equipped with Mitutoyo’s patented Advanced Onsite Sensor (AOS) induction technology. Offering 0.01 mm (0.0005 in) resolution, 4-way measurement capability, and absolute origin memory that eliminates repetitive zero-setting, it delivers unmatched precision for machine shops, quality control labs, and aerospace manufacturing.
Features & Benefits
-
Patented AOS Induction Sensor: Advanced Onsite Sensor uses electromagnetic induction to ensure stable measurement even when scale surfaces are exposed to coolants, water, or oil mist.
-
ABSOLUTE Linear Encoder Technology: Retains the calibrated reference point permanently on power-up, eliminating repetitive zero-setting and eliminating overspeed counting errors.
-
Standard 4-Way Measurement Capability: Precision-ground measuring faces accommodate external diameter, internal diameter, step height, and depth bar measurement.
-
High-Visibility Digital Readout: Features an oversized 9 mm character LCD display for effortless reading under industrial lighting with instant inch/millimeter unit switching.
-
Exceptional 18,000-Hour Battery Runtime: Low-power consumption circuitry provides up to 3.5 years of continuous normal operation on a single SR44 silver-oxide button cell.
-
Hardened Stainless Steel Construction: Lapped sliding surfaces and hardened beam components guarantee smooth movement, scratch resistance, and long-term metrology stability.
Description
Recognized globally by machinists, toolmakers, and metrology inspectors as the benchmark for handheld dimensional inspection, the Mitutoyo 500-196-30 delivers dependable, micron-grade repeatability across a 0 to 150 mm (0 to 6 inch) measuring span. Engineered with Mitutoyo’s electromagnetic induction AOS (Advanced Onsite Sensor) technology, this caliper resists the interference of machine oils, airborne dust, and coolant droplets that cause erratic count errors in standard capacitive digital scales, ensuring uninterrupted operation directly inside CNC machining centers and metal workshops.
