A uniquely designed caliper, provides precise measurement at an affordable price. The 0-100 mm scale is what sets this instrument apart from other clinical calipers on the market that only have a 0-60 mm scale. The 0-100 mm scale is easy to read and it allows you to accurately measure the skinfold thickness of a larger portion of the population than the other calipers. The spring-loaded arms and pivoting tips adjust automatically for parallel measurement of skinfolds, and the circular tips provide comfort to the patient. The tension spring provides constant pressure over the entire operating range, meeting the pressure requirements of 10g/mm2. The caliper is lightweight, durable, and never needs calibration. Measurement Range: 0-100mm. Size: 5"x6"x0.6"
