Precision range and accuracy: 115 mm range with 0.1 mm accuracy; clear graduations for hole, slot, and diameter measurements in tight spaces, helping you verify small features quickly and reliably. Dualscale, stainless steel construction: doublescale wedges and tapered gauges in stainless steel provide precise millimeter and inch readings for narrow gaps and welding inspections, improving consistency across metric and imperial work. Durable, reliable calipers: stainless steel calipers with sharp, precise reading edges and corrosionresistant durability, suitable for both workshop and field measurement tasks. Versatile for professionals: designed for welders, inspectors, and mechanical engineers requiring multifunction dimension verification in confined workspaces, delivering dependable results in restricted areas. Use scenarios: Welding inspection in tight joints: measure hole diameters, slot widths, and bore sizes where space is limited, ensuring welds meet specification. Onassembly checks: verify multiple dimensions (hole, slot, and diameter) in a single setup when clearance is restricted. Field maintenance in confined spaces: perform accurate measurements in equipment or structures with limited access while resisting corrosion in varying environments.
