Used to measure the thickness of subcutaneous tissue, or “skinfolds”. Once recorded, these measurements can be translated to body fat content as a percentage of body weight. It should be noted that these percentage figures vary with age and sex. Lightweight and aluminum, the caliper has a large, easy-to-read scale that extends to 70 mm. The Skinfold Caliper comes in a protective carrying case. “Floating tips” at the ends assure accurate and reproducible results. Quick and simple to use. Just take three measurements at each skinfold site. The final thickness is the average of these readings. In addition to the protective carrying case, the caliper also comes with a fully illustrated instruction manual which features body fat conversion tables for adults and children.
