Height gauges incorporate a base, vertical column, and an adjustable scriber or dial indicator which enable measuring vertical dimensions and scribing parallel lines. In metrology labs, granite based precision models are commonly used because they offer high levels of resolution, up to 0.001 mm. Workshop models which are magnetically mounted Steel bases have lower resolution of 0.01 mm. Height gauges are crucial in ensuring consistency with tolerances of ±0.005 mm in the height of stamped parts and injection molds during casting inspection and when setting up press tools.
