What is a spirit level's sensitivity?
The sensitivity of the vial determines how quickly the bubble moves when one end of the spirit level is lifted. 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.
What is a spirit level's tolerance?
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.
