LumiScale is a self-illuminating levelling staff for digital levels for use under unfavourable light conditions such as underground and tunnelling construction projects. With regard to its precision, self-illuminating levelling staff LumiScale fulfils the norm DIN 18703. The LumiScale graduation is back-lit 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. LumiScale is available with bar codes for all common digital levels. Product Ref.-No. 340 220 LumiScale with Trimble bar code.
