This is one of the first multi-functional mechanical column scales in the industry. It displays not only the weight, but the nutritional condition and BMI information of the patient as well. When a patient steps onto the Seca 756, a BMI disc of contrasting color is set in motion on a clear, large dial. A height scale is printed next to the small display window. Once the weight of the patient is determined, it is easy to read the BMI range, which is split up into obesity, overweight, normal, and underweight – all in contrasting colors. Additional benefits of the 756 include a flat tread area, practical transport castors, and an optional measuring rod.
