PRECISE AND RELIABLE AUTOMATIC COMPENSATOR OF AUTOMATIC LEVELING MACHINE
The B series levels incorporate the most precise and reliable compensator available in the market today. Four super-high-tensile suspension wires and magnetic damping system ensure accuracy and stability even when exposed to temperature changes, vibrations, or shock.
Superior Telescope : The optimally designed telescope provides an exceptionally bright and sharp view that reduces operator’s eye strain. Ultra-short focus distance of 20 cm from end of telescope makes it easiest to use in confined spaces. Two-speed focus knob switches between coarse and fine for even faster operation (B20).
Quick Collimation : The endless horizontal motion drive screw can be operated with either hand for fast and easy aiming
Horizontal Angle Measurement: Horizontal angles can be read in 1° or 1gon units. The freely rotatable circle allows any angle reading from zero. Right angles can be quickly set for layout and alignment tasks.
Rapid Setup: Sokkia’s B Series fit both domed and flat head tripods. The circular level can be seen on a pentaprism or plane mirror located beside the telescope eyepiece.
Stadia: The stadia lines on the reticle allow distance measurement to be carried out. Simply multiply the staff length between the top and bottom stadia lines by 100.
