Normacheck perpendicularity test instrument allows practically, quickly and directly to survey perpendicularity and straightness errors with the lowest tolerance. No tare, squares or cubes are required. It is always ready to be used since the structure in granite and the working precision assure stability and repetition. The sliding of the gauge stand (not supplied) is manual, based on linear ball slide. This tool is a simplified version of the motorized model Pertest, requires no compressed air, is lighter to handle and still has a good accuracy both of straightness or perpendicular. The trolley tool is actionned by the operator and tends to return to its own weight in the low position.
