83SW 3 Vial Angle Finding Double Plumb Girder Levels
This pressure-cast light metal level has two milled measuring surfaces. It is robust and very practical: its two handholds make it very comfortable to use.
The horizontal vial can be read from all four sides and both the vertical vials from three sides, whether in normal position or overhead.
With an additional angle finding vial. The second vertical vial can be rotated so that you can determine the angle of the inclination that you are measuring.
Measurement accuracy: in the normal position 0.029° = 0.5 mm/m. For overhead measurements: 0.029° = 0.5 mm/m.
Angular measurement tolerance: ± 0.3°.
Length. 400mm. (16in).
