Abstract: A pneumatic plug gauge has been developed in the context of the invention. This plug gauge comprises a first measuring channel which can be connected to a pressure medium source and opens into a first outlet for the pressure medium, which outlet can be directed to a surface of the workpiece to be tested. According to the invention, this plug gauge is designed to determine the tilt angle between a section on the surface thereof and a region opposite this section on the surface of the workpiece by virtue of the first outlet being arranged at one end of the section and at least one second outlet being provided, which second outlet is arranged at the other end of the section. It has been recognized that the admittedly high precision of pneumatic length measurements can be converted in a particularly advantageous manner to high precision of the angle measurement in this manner. The tilt angle can be measured at least with an accuracy of less than one tenth of a degree.
