The seca 755 is one of the first mechanical column scales which, in addition to displaying the weight, also displays the respective nutritional condition of the patient with the BMI function. When the patient mounts the scales, a "BMI disc" of contrasting color is set in motion below the very precise weight display in the large, clear dial. It is visible in a small window next to which a height scale is printed. Once the weight has been determined, it is easy to read the BMI range which, with contrasting colors, is split up into underweight, normal and overweight as well as adiposity (abnormally overweight). A flat tread area and practical transport castors are further advantages of the seca 755. It can also be converted into a complete measuring and weighing station by fitting the optional measuring rod seca 220.
