Engineer's scale

The Triangular scale, triangular or prism scale (also prism or Maßknüppel ) is a ruler with six different scale scales. To accommodate this scale of a ruler, is the benchmark in cross section star-shaped and this "star" three units.

Triangular scales are 30 cm long usually. Today, these are made from a polymer material, or manufactured in high-quality versions of light metal (aluminum). In the selection of materials, particular emphasis is given to the dimensional accuracy. Formerly known triangular scales were made ​​of wood and with scales made ​​of aluminum, or later with a high-quality polymer material, which should be heat-resistant and dimensionally stable, covered. Will use the Triangular scale, especially when working with different scales and time-consuming conversion operations shall be avoided.
