Increased gear ratio for shock and vibration
Sokkia B-Series automatic levels feature enhanced reliability under all environmental conditions. Tough, compact bodies are tightly sealed against water, humidity and dust (IPx6). The B-Series levels also provide quick setup, easy sighting, and superior durability against vibration and shock, ensuring the increased productivity over an extra-long period of time.
Models: B20 - 40x, B20 - 32x, B30 - 28x, B40 - 24x.
Precise, Reliable Automatic Compensator
The B-Series levels incorporate a very precise and reliable compensator. The technological superiority of Sokkia auto levels has been proven since the release of the best-selling B2 model in 1963. 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
Optimally designed telescope provides exceptionally bright and sharp view that reduces operator's eye strain. Ultra-short focus distance of 20cm (7.9 in.) from end of telescope makes it easy to use in confined locations. Two-speed focus know (B20) switches between coarse and fine for even faster operation.
Quick Collimation
Endless horizontal motion drives can be operated with either hand for fast and easy aiming.
Horizontal Angle Measurement
Horizontal angles can be read in 1° or 1gon units. Freely rotatable circle allows any angle reading from zero. Right angles can be quickly set for layout and alignment tasks. The readout window is conveniently located on the instrument base - directly below the eyepiece.
Stadia
The stadia lines on the reticle allow distance measurements. Simply multiply the staff length between the top and bottom stadia lines by 100.
