SURVEYING INSTRUMENTS World-Proven Precision and Durability Sokkia B series automatic levels feature enhanced reliability under all environmental conditions. Tough and compact bodies are more 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 an extra-long period of time. ■ Precise, Reliable Automatic Compensator The B series levels incorporate the most precise and reliable compensator available in the market today. The technological superiority of the Sokkia automatic levels has been proven since the release of the best-selling B2 model in 1963. Four super-hightensile suspension wires and magnetic damping system ensure accuracy and stability even when exposed to temperature changes, vibrations, or shock. Magnetic field is generated in a compensator. …the eddy current creates a force against the conductor’s motion. When a conductor moves… …the motion generates electro-magnetic induction to produce eddy current in the conductor, and… ■ Quick Collimation Two knobs of 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. ■ Rapid, Easy Setup ■ Superior Telescope Optimally designed telescope provides exceptionally bright and sharp view that reduces operator’s eye strain. Ultra-short focus distance of 20cm (7.9in.) from end of telescope* makes it easiest to use in confined locations. Two-speed focus knob switches between coarse and fine for B20 B40 B20 B30 B40 even faster operation B30 (B20). *30cm (1ft.) from instrument center Telescope Telescope A domed-head tripod makes setting up faster and easier even on inclined, uneven grounds. The B series levels also fit flat-head tripods. The circular level B20 B30 can be seen on a pentaprism or plane 32x 28x Telescope Telescope mirror located beside the telescope eyepiece. B20
