Description
Sokkia B series automatic levels feature enhanced reliability under all environmental conditions. Tough and compact bodies are tightly sealed against water, humidity and dust (IPX6). The B series levels provide quick setup, easy sighting, and superior durability against vibration and shock, ensuring the increased productivity over long periods of time.
Precise and Reliable Automatic Compensator
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.
Optional Accessories
Diagonal Eyepiece DE16 (B20)
Ideal accessory for working on jobsites where there is little space to move.
40x Removable Eyepiece EL5 (B20)
Increases the standard 32x magnification to 40x.
Diagonal Eyepiece DE22 (B30/B40)
A diagonal eyepiece facilitates work in tight spots with little space behind the instrument.
