The mobile base 2 and the movable cups 4, 5 have respectively their scales 11, 12, 13 to control their movement. The hinge 14, is rigidly attached to the housing 1 or the support 3, allows the rod 15 to move in both the horizontal and vertical planes. Level 16 on the rod 15 are required to control the horizontal rod, which can be caused risks or permitted area with the maximum allowable slope.The device operates as follows.When installed in the autoclave device base fixed bearing 3 on the rail of the autoclave and the rotation of the Cup 4 on a scale of 12 check the correct position of the rail relative to the body of the autoclave, and then moving the movable support 2 check the size of the track rails on the scale 11, and the rotation of the Cup 5, the position of the second rail on the scale 13 relative to the body of the autoclave, the arrow 8 on the scale 10 will show the presence or absence of differential rails height. Moving the rod 15 of the housing 1 (transport position), by a hinge 14 set the bar 15 on the surface of the rail and on the testimony of level 16 estimate the slope of the rail in the autoclave. Then the device rotates about the axis in the horizontal plane and check similarly in the positioning opposite one another. The presence of articulated rods, without resorting to additional devices, to measure the horizontal rail in the autoclave. 1.
