Glass circular levels / Bullseye levels /

Circular Bubble Levels with an aluminium body

All precision circular levels / precision bullseye levels / Bubble levels are produced with a precision ground glass lens and are available in sensivities from 5 to 30 arc minutes.

Bubble levels / Bullseye levels are used as a type of zero indicator instrument for checking horizontal inclination in e.g. spirit levels, inclinometers, metrology instruments and machine constructions.

All of our circular levels are made with an internal bubble ring to eliminate planar parallaxes.
