This seca is capable of much more than a standard hand-rail scale. It combines five functions: Thanks to its railing and an extremely flat platform, even persons with balance problems can safely weigh themselves. Equipped with a high capacity and a stable design, this multi-functional scale enables supported weighing while standing. Thanks to its extra large platform, a chair can be added in effortlessly, so that convenient weighing while sitting is also possible. The seca 645 can also be fitted with a measuring rod, and the standing scale is transformed into a stable measuring and weighing station. The new multi-range display with pushbutton switch over between weight ranges, the BMI function to assist with interpretation of nutritional conditions, and castors enabling mobility all do their part to make the seca 645 a much used allrounder.
