The red and green arcs can be mounted in different lengths and positions on the window, even on already installed instruments. Thus, without any great effort, any scale range desired can be defined. When ordering small quantities of instruments, the new accessory (model designation 910.33) is a cost-effective alternative to the corresponding dial layout.
The adhesive labels have a long shelf life due to their temperature- and UV-resistant material. They are also translucent. Therefore, the dial remains easy to read.
