Sokkia B Series Automatic Levels
Sokkia’s B series automatic levels feature enhanced reliability under all environmental conditions. Their rugged, compact bodies are tightly sealed against water, dust and humidity (IPx6). Quick setup, easy sighting and superior durability against vibration and shock ensure increased productivity.
The B series levels incorporate field-proven precise and reliable compensator for accuracy you can rely upon. The optimally designed telescope provides exceptionally bright and sharp view that reduces operator’s eyestrain. Quick collimation and horizontal angle measurement combine for fast and easy aiming of layout and alignment tasks.
