This device allows a correct evaluation of the nutritional status and the sectoral distribution of adipose tissue. Raises a fold of skin with your fingers and measures its thickness by the forceps: on the top edge a scale in millimetres and an arrow measures the skin fold (triceps, subscapular muscles, etc...) with an accuracy of about ½ mm. The coloured bands placed near the scale allow a simultaneous comparison of the measured value with referential percentages related to men and women. This information is included in the manual provided with the unit, which helps an easy interpretation of the values.
