The 300mm (12") Draper Expert Digital Vernier Calipers provide extended measuring capacity for larger components and workpieces. This longer length makes them ideal for measuring bigger parts, deeper recesses, and applications where the extra reach is essential for accurate measurement. Equipped with an extra-large LCD screen, these professional calipers display readings clearly in both metric and imperial units. The hardened stainless steel construction guarantees durability and precision over years of use, whilst the thumb roller and locking screw ensure smooth, controlled movement with secure positioning. The convenient zero button can be activated at any point to enable differential measurements, and the auto power-off feature helps preserve the included LR44 battery by switching off after five minutes of inactivity. Supplied in a protective plastic storage case for secure storage and transport.
