Bull's eye levels
Elesa offers bubble levels which consist of a hollow body containing a fluid with a gas bubble, and are used how level a surface is. The position of the gas bubble in the fluid shows the angle and the direction in which the object is inclined with respect to the horizontal plane. The hollow body containing the contrast fluid and the gas bubble floating in the upper part are always at the highest point.
The transparent upper surface contains a mark to clearly indicate the central position. Bubble levels are available as bull's eye levels for bidirectional or cylindrical levels of unidirectional measurements. The single directional spirit levels are available with rear or bottom insulation plaster and are ideal for detecting the incline angle in a direction along the axis of the level. The bidirectional spirit levels simultaneously detect the tilt angle and the angular position of a floor.
