Bull´s eye levels GN 2277 are used to check the horizontal position of jigs, machines, devices, appliances and instruments.
The spirit levels are aligned in relation to the reference surface such that the bubble is located inside the marking ring once the vertical position of the contact surface is reached.
Bull´s eye levels and levelling elements - in this example, levelling elements GN 355 and assembly tool GN 355.1 - are ideal to use when a holding plate is to be brought into an exact horizontal position. Even after the initial adjustment, the bull´s eye level remains in the unit so that the correct alignment can be checked and adjusted again
