Calibration Dowel Thickness Gauge for Harpenden, Skyndex Skinfold Caliper 20mm & 35mm Metric

Description

Use this 2 step calibration to certify calibration of your Harpenden, Skyndex, or Slim Guide skinfold caliper. A cylindrical dowel, rather than a flat block, is necessary for proper alignment of the tips as they come into contact, which ensures an accurate measurement.
