Square Level

About Sensitivity

Sensitivity (mm/m) represents either height or angle of gradient which is required to move main bubble a scale.
For example, you will know there is 0.02mm height difference 1m away from where you measure, when the main bubble moves a scale.

NOTE 

0.02mm/m is 4 seconds = 0.0011°
0.05mm/m is 10 seconds = 0.00277°
0.1mm/m is 20 seconds = 0.0055°
