Due to their cylindrical design, bull´s eye spirit levels GN 2281 are suitable for installation in plates and housings where they serve to check the horizontal position of jigs, machines and devices.

Bull´s eye levels are not aligned, i.e. adjustment to the vertical position must be ensured by aligning the receiving component.

The black housing of the version ALS creates a reflection at the edge of the bubble which significantly improves the readability. Version KT is available with contrast ring inside the air level housing (Identification no. 2) which creates the same effect.

Alternatively, the contrast can also be improved by a dark surface inside the mounting bore hole.
