Elesa’s BEL series of Bull’s eye circular spirit levels provide high-quality centre bubble levelling in a variety of easy mounting formats, for use where frequent relocation is foreseen or where exact level is required to be checked – for example on portable equipment or especially sensitive instrumentation. Mono-directional screw-fit levels are also available for use singly or in pairs at 90°.
BEL Bull’s eye levels come in flanged front or rear housings or without flanges for rear mounting (via stud) or for insert fitment either by interference or to be glued-in place. They demonstrate excellent bubble sensitivity of #30: movement of the bubble by 2mm for an inclination of the body by 30 angle minutes with respect to the horizontal.
