High-precision crane scale: weighing range 0.3lb-880lb (0.1kg-400kg), error margin ±1lb. The measurement unit can be switched to LB/KG/N. High-quality industrial crane scale: The crane scale body is made of solid cast aluminum material, making the crane scale stronger and more durable. Suitable for farm, hunting, traveling and other indoor and outdoor activities. Unique features: peak hold, automatic power-off setting, calibration mode. Peak hold means that when an object that is not stationary is weighed, the number keeps jumping. The VEVOR crane scale will take samples from these numbers to calculate an average, which is close to the true weight. Weigh & Measure in One: Say goodbye to that extra tape measure cluttering your toolbox. Our digital hanging scale hides a sneaky 1M measuring tape inside. Weigh and measure length all in one go – it's a twofer! With precise markings and a smooth pull, just give it a tug, and you're in business. Hooked on Security: In order to prevent the hook from falling off and being lost, VEVOR hanging scale is designed with a safety clip at the S-shaped hook. Package contains 2 AA batteries (non-rechargeable).
