When accuracy matters, choose the all-in-one load cell that is strong, smart, and ultra fast.

LineScale 3i is a high-strength, high-speed load cell designed for the demands of rope rescue, rope access, and technical rigging. Milled from solid aluminum with a 90 kN minimum breaking strength and PPE certification, it excels as a single master point in critical operations such as drop testing or twin tension rope systems (TTRS). The clear digital display and Bluetooth connectivity provide instant feedback in the field, while the rugged build and included components make it easy to deploy, transport, and protect.

Engineered for performance and insight, LineScale 3i logs up to 50 hours of high-resolution data and measures up to 1,280 samples per second—capturing every peak load with unmatched precision, even in dynamic events. With storage for over 200 million data points and easy USB downloading, post-operation analysis is quick and intuitive. Through its long battery life, water resistant rating, and free app, LineScale 3i ensures you’re fully equipped for the task, whether you’re monitoring anchor forces or evaluating system performance under real-world loads.

Both a next-level teaching tool and a powerful addition to any rigging cache, LineScale 3i enhances testing protocols, improves training outcomes, and supports safer decision-making in live operations.
