The accuracy of the LumiScale is classified between conventional levelling staves according to DIN18703 and Invar levelling staves according to DIN18717.
Thus, the LumiScale staff is also suitable for challenging and complex levelling work. In contrast to an external illumination, the graduation of the staff is back-lit by means of an electro-luminescent foil. This method provides extremely smooth and even illumination without the formation of shades that might cause errors in measurement.
It works without saying that the LumiScale staff is manufactured in Germany with the proven NEDO quality. The rugged, torsion-free aluminium box secion, corrosion-free fittings and elaborate solutions for details – such as the illuminated 12’ bull’s eye level – allow for a long service life of this product and have you enjoy your work. The ergonomically designed handle is located in the centre of gravity of the staff and facilitates energy-saving and comfortable transport from one point to another.
