TESA Spirit Inclinometer with Protractor and Micrometer Element
Enables the measurement of angular deviations in any position of a cylindrical or flat surface.
Instrument features: prismatic measuring face (shafts Ø 17 to 80 mm) (DIN 877 + DIN 2276/1). Scale range: 2x 180°.
The adjustment is executed by disengaging the micrometer element by pressing in the direction indicated by the arrow. Afterwards the vial is oriented manually before engaging the micrometer element and executing the fine adjustment with the latter.
1 scale division = 1 degree.
1 division of the micrometer element = 1 Arcmin
Vial with sensivity of 0,3 mm/m (= 1 Arcmin).
Error limit = 1,5 Arcmin
