LumiScale is a self-illuminating leveling rod for digital levels for use under unfavourable light conditions such as underground and tunneling construction projects.
With regard to its precision, LumiScale is classified between regular leveling rods (DIN 18703) and precision Invar leveling rods (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 University of Graz, Austria, have proven that measuring errors are eliminated thanks to the equable illumination of the graduation. For this reason the LumiScale technology is superior to an external illumination of the graduation.
