MISUMI Water Levels
A bubble level is a measuring tool for measuring the angle in relationship to the ground and checking for level. Used when angle measurement is required, such as at construction sites, electrical work, plumbing, etc. The structure has a liquid such as alcohol, ether, etc. contained in a circular glass container. Liquid and air bubbles are contained inside the container, and air bubbles move depending on the angle of the object to be measured. It is possible to measure horizontally and the inclination angle with the bubble position. Bubble levels come in a variety of shapes, such as flat, round, square, etc. for measuring flat or spherical objects. There are also precision bubble levels that can measure with higher sensitivity, inclinometers that measure the tilt angle, etc. Others have differing functions, such as those that display the measured angle digitally, those that have a magnet and can be attached to the object to be measured, etc.
