Easy to use, a spirit level is a must-have tool in all toolboxes. Used for construction work, the spirit level is used to determine and verify the accuracy of the verticality or horizontality of an element.
What is a spirit level?
A spirit level is a general metal tool that has a completely flat surface and has one to two colored tubes each containing a liquid and an air bubble. It is this air bubble that will allow you to perform your measurements. One of the tubes allows a horizontal measurement and the other vertical. The bubble will always go in the direction of the slope, upwards.
How does a spirit level work?
A spirit level is a tool that measures the inclination of a support relative to a horizontal base. Entirely mechanical, its operation is articulated around one or even two transparent tubes that contain a generally yellow liquid in which is imprisoned an air bubble. It is this air bubble that displays the degree of the angle formed by the element on which the spirit level was positioned.
How to use a spirit level?
- To check the horizontality or verticality of your support, take your bubble level and place it directly on the support.
- If the bubble of your level is between the two lines, it is because your support is perfectly horizontal or vertical.
- Conversely, if the bubble is not exactly between the two marks, it is because the support is not horizontal or vertical. To obtain a proper angle, the element must be handled until the bubble is perfectly wedged between the two marks.
- This technology is also used on some devices such as tripods. The bubble level, whose shape then takes on the appearance of a sphere, makes it possible to position the tripod ideally and to place a laser level there for example to obtain more precise measurements.
- The bubble took the direction always goes in the direction of the top of the slope.
Choose a level large enough to measure horizontality and verticality over a sufficient length.
