Waterpas Sokkia B30

Product Information and Details 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. Features 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-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 ( 7.9in.) from end of telescope makes it easiest to use in confined locations. 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 1 gon 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. Easy to Adjust Reticle adjustment is made with one screw. Circular levels vial is adjusted with two screws. Both adjustments are simple and fast with provided tools.
