DS22, DS23 are used in 3” and 4” order leveling and in geodetic control, construction of roads and industrial applications. The DS22 with FS1 may be used in 2” order leveling or in monitoring struc - tural deformation etc. The use of automatic com - pensator speeds up work and improves accuracy. They can be operated in the temperature from - 30℃ to + 50℃.
Equipped with a press button for compensator checking.
Dismountable eyepiece, assorted accessories, such as: Diagonale Eyepieces.
Adopt crossing suspender frame and compen - sator of air damper.
