of Right Angles


Granit Master Blocks are often to small and always too heavy. The T430 is a real alternative to these cumbersome static slabs. The ProLine® System is highly versatile and more precise supporting measurement over more than 10 meters if necessary.

Definition of Perpendicularity
Right Angles

The Tolerance Zone is here like straightness defined by two parallel planes above and below the data. The difference here is that the tolerance lines must be orthogonal (at right angles) to a reference line. Practically the reference line is either defined by two points or the “best fit line” through a large number of measured points.
