Universal Road Ruler KONDOR-N for Accurate Measurement of Road Surfaces

The universal road rail is intended for measuring unevenness of bases and coverings of motorways and aerodromes. The KONDOR-N rail is a monolithic construction made of a hollow rectilinear profile of anodised aluminium alloy. The lath body is marked with a three-metre metric scale with a graduation value of 5 mm, which has five reference marks indicating the places of measuring the gaps under the lath with the help of a wedge gauge. A wedge gauge for measuring unevenness and thickness of pavements is supplied with each lath. The central part of the KONDOR-N road lath is equipped with a slope gauge in the form of a measuring head with a limb connected with the level for setting the lath in a horizontal position. An eclimeter for slope steepness measurement is mounted in the inner cavity of the central part, which is a freely rotating disc with a counterweight on which a symmetrical scale for slope steepness measurement is applied.
