The LineScale 3i+ Load Cell is a high-strength, high-speed load monitoring device engineered for rope rescue, rope access, technical rigging, industrial testing, and load analysis applications. Milled from solid aviation-grade aluminum and certified as PPE equipment, the LineScale 3i+ provides exceptional strength, precision, and reliability while serving as a single master point in demanding rigging systems, drop tests, and twin tension rope systems.
Designed to deliver actionable data in real time, the LineScale 3i+ captures loads at up to 1,280 samples per second, ensuring accurate measurement of peak forces during dynamic events. Bluetooth connectivity and the free companion app allow users to monitor and record data remotely, while onboard memory stores up to 50 hours of logging and more than 230 million data points. The latest generation includes improved temperature compensation, enhanced torsion resistance, rounded load eyes for better textile compatibility, increased screen durability, a compact EVA hard case, and a waterproof USB flash drive. Fully equipped and ready for deployment, the LineScale 3i+ is an essential tool for rescue professionals, rope access technicians, trainers, industrial users, and rigging specialists.
