An ergonomic, analogic, iodized aluminum caliper with a non-friction bushing, designed to respect the specifications for skinfold caliper building outlined by Edwards and colleagues (BJN 1955), that formed the basis for the Harpenden and Holtain calipers. Resolution to 1.0mm. An outstanding feature is that the indicator branch has a set of two Allen-type screws to allow calibration, and its accompanying Allen wrench.
