LumiScale is a self-luminous leveling staff with a barcode for the use in underground or in tunnel constructions. With regard to its precision LumiScale is classified between traditional leveling staffs (DIN 18703) and precision leveling staffs (DIN 18717).
The LumiScale graduation is backlit via an electroluminescent foil which uniformly illuminates the entire graduation without any shades. Extensive tests, performed by the Graz University, have proven that measuring errors are eliminated thanks to the continuous illumination of the graduation. For this reason the LumiScale technology is superior to an external illumination of the graduation.
This LumiScale leveling rod has the Leica DNA bar code.
