ESL2

Precise Automatic Level

ESL2 is used in geodetic control, construction of roads and industrial applications. The ESL2 with ESM1 can supply higher accuracy and be used in monitoring structural deformation etc. The use of automatic compensator speeds up work and improves accuracy. ESL2 supply the possibility to operate in the temperature from -30℃ to +50℃.

1.      Equipped with a press button for compensator checking.

2.      Dismountable eyepiece and assorted accessories such as Diagonal Eyepieces.

3.      Adopt crossing suspender frame and compen­sator of air damper.
