Vial sensitivity does not reflect the accuracy of a level vial. It describes how easily the vial bubble moves when it is shifted from its level position to an unlevel position. Our technical machines which have been constructed especially for grinding optical lenses are capable to produce exact sensitivity. The air bubble reacts exactly to all directions of motion. Therefore our circular spirit levels are used in sensor Technology, too.

Results of the measurement of the bubble movement

We can recommend a suitable sensitivity based on your application.Our circular spirit levels have a good performance over a wide temperature range. Stahl Präzisionslibellen pays particular attention to the environment.
