GG Tech manufactures test and measuring instruments to verify the dimensional quality of mass-produced parts. Devices of this type allow you to easily check the deviations of the geometry of any part against the set criteria. They can be equipped with dial indicators facilitating the reading of the deviation value or with tolerance fields on the basis of which the controller qualifies the position of a given dimension in the required deviation field. Gauges and measuring instruments speed up control, eliminate the need to have universal measuring tools, the use of which is impossible when measuring shapes and points on curved surfaces. The ease of handling and qualifying parts with the instrument eliminates the need to maintain a qualified metrology staff.
