The instrument is a combination of the "classic" spreading caliper and the "classic" pelvimeter, fitted with sliding arms and rounded ends and covering the range from 0 to 430 mm. The instrument may therefore be used to measure not only the dimensions of the head, but also selected body width or depth dimensions in children up to the age of about 15 (e.g. biacromial width, biiliocristal width, bispinal width, bitrochanteric width, transverse width of chest, biepicondylar width of humerus, biepicondylar width of femur). Made of light stainless materials (weight of 182 g), this highly practical instrument, whose arms are connected with a steel joint, to improve the balance of the gauge, contains a removable magnifier for easier reading of the scale.
The magnifier is fitted on the instrument slantwise, in the viewing direction.
