NEDO LumiScale Illuminated Levelling Staff, with a barcode

An illuminated LumiScale is a levelling staff suitable to work underground, in tunnels or in bad lighting conditions. In terms of accuracy, LumiScale is classified between traditional staves (DIN 18703) and invar staves (DIN 18717). The graduation is illuminated with electroluminescent foil that, contrary to external lighting, illuminates the whole graduation and does not form shades. Extensive tests run at Graz University prove that continuous illumination of the graduation prevents measuring errors.
