Manufacturing tolerance is the sum of all possible minor and microscopically small errors during production. Tolerance is thus the divergence from sensitivity, and the smaller the value the better.
Hultafors spirit levels contains block vials
For the highest accuracy the finest spirit levels from Hultafors feature block vials. Hultafors block vials have a defined inner contour and are symmetrical around both the X- and Y-axis.
tolerance for standard and reversed position
The tolerance of all vials used is calculated for both standard and reversed position. This allows for exact measuring both when measuring atop a surface, and from below.
How to measure from below
Remember, when measuring against a surface from below always to turn the spirit level upside down. This ensures that you always measure with the bottom surface of the spirit level, since it is this surface the vials are calibrated against.
Certified in accordance with ISO 9001.
At Hultafors all spirit levels are thoroughly checked before leaving the factory.
To guarantee the accuracy of our spirit levels, our manufacturing process is certified in accordance with ISO 9001.
Libella 2000 - The extendable level
Expand you idea of leveling
Spirit levels can be too long or too short or too un-precise. Then there is Hultafors Libella 2000 – a spirit leveling system, expandable from 310 mm to 3100 mm, five times as sensitive as standard spirit levels.
5 facts about our vials
Learn more about the vital vials
The fluid-filled containers that give you a level reading are called vials. The liquid in the vials is usually oil or alcohol so that the air bubble inside can move freely.
Why sensitivity matters

The higher the sensitivity the more precise the spirit level is. This means that the bubble of a more precise spirit level reacts more when one end of the spirit level is lifted.
