Coordinate Caliper (Aichel Type)

GPM Model 116    Price:  $4,069

Product Details

This coordinate caliper has a span of 20-300 mm and an overall length of 37 cm.  Vernier readings to an accuracy of up to 1/10 mm can be made.

The steel rulers, fitted at right angles to the measuring bar, one of which is displaceable, are both 135 mm in length. The measuring bar, attached at the middle to one slide, is graduated in millimeters from 135-0 mm and from 0-50 mm.

Application: It is often used in craniology to determine the height or depth of a point relative to a track. The pointed ends of the steel rulers touch the boundary points of the track. The height or depth of a point to this so fixed distance is measured with the third, also sharpened steel ruler - the so-called coordinate arm - which is movable on a slide between the other two rulers along the metal rod and also perpendicular to this.

Caution: For cleaning please do not use acetone or acetone-containing cleaning agents.
