Long Jaw Digital Calipers-Industrial Use Digital Caliper

The Long Jaw Digital Caliper is a heavy-duty precision measurement instrument engineered specifically for industrial large-scale measurement applications. Unlike standard digital calipers limited to 150mm–200mm ranges, this large-range digital caliper is designed to handle oversized workpieces with measuring capacities from 300mm up to an exceptional 3000mm (120 inches) , making it the ideal solution for heavy machinery manufacturing, aerospace fabrication, shipbuilding, and large-part quality inspection

Key Features

Extended Measuring Range
Available in capacities from 300mm to 3000mm, this 3000mm digital caliper eliminates the need for multiple measuring tools when working with large workpieces, significantly improving measurement efficiency and workflow

With a resolution of 0.01mm (0.0005 inches) , the Type III caliper delivers the high accuracy required for precision manufacturing. Accuracy grades range from ±0.04mm for shorter ranges to ±0.26mm for full 3000mm capacity, ensuring reliable results across the entire measurement spectrum

Heavy-Duty Construction
Built with a robust hardened stainless steel scale and measuring jaws, this industrial-grade measuring tool withstands demanding workshop conditions. The beam and guiding elements are constructed from lightweight yet rigid materials-aluminum or carbon fiber options available-reducing operator fatigue during extended use while maintaining structural integrity

Large-Size Measuring Jaws-Long Jaw Digital Caliper
Equipped with extended jaw lengths up to 300mm, this caliper easily accommodates large-diameter workpieces and provides stable contact surfaces for accurate outside measurement
