Which instrument is used to check whether an object is level or plumb?

Explanation:
The main idea here is alignment. A level uses a bubble in a liquid-filled vial to show when a surface is horizontal. When the bubble sits centered between the marks, the surface is level. Many levels also include a vertical vial, so you can check plumb (vertical alignment) by ensuring the vertical bubble centers. This makes a level capable of verifying both level and plumb orientations. Protractors measure angles, calipers measure distance, and rulers measure length. None of these tools indicate whether a surface is level or plumb, which is why the level is the appropriate instrument.
