General Information on bull's-eye levels and screw levels

GN 2278 bull's-eye levels are used to check the horizontal position of jigs, machines, devices, appliances and instruments.
The housing is grooved at its lower diameter d3, making it easier to mount in place, e.g. by gluing.
The spirit levels are aligned in relation to the reference or contact surface, so that the bubble is centrally located inside the marking ring once the horizontal position of the contact surface is reached.

Available upon request:
• Filling: green-transparent
• Other sensitivities
• Housing in brass or stainless steel
