With 40x magnification, the Sokkia B20-25 Automatic Level provides surveyors, builders and engineers highly accurate leveling, angle, height, as well as distance measurements. Accurate up to 1/32 inch, this optical instrument offers quick setup, easy sighting and superior durability against vibration and shock with its built-in compensator.
To reduce eye strain, the B20 25 auto level features a superior telescope designed to provide exceptionally bright and sharp view. It also has an ultra-short focus distance of 7.9 inches from end of the telescope, making it easy to use in confined locations. With an internal compensator, this survey and construction tool levels the line of site within the range of ±15 arc-minutes and an accuracy of 0.3 arc-second.
You have the option for a diagonal eyepiece that facilitates work in extremely tight spots and an optical micrometer for increased accuracy up to 0.5 mm. In addition, a light unit is available for leveling in low light conditions.
2-Speed Focus Knob
The Sokkia B20 has a two-speed focus knob that automatically switches between coarse and fine for even faster operation. In addition, the two knobs of endless horizontal drives can be operated with either hand for fast and easy aiming.
Horizontal Angle and Distance Measurement
Horizontal angles can be read in degree or gon units and the readout window is conveniently located below the eyepiece. The horizontal circle is also freely rotatable allowing any angle reading from zero. In addition, the stadia lines on the reticle enable distance measurements by simply multiplying the staff length between the top and bottom stadia lines by 100.
Rapid and Easy Setup
The B series automatic levels fit flat-head and domed-head tripods for faster setup even on inclined, uneven grounds. With the included tools, you can easily perform reticle and circular level vial adjustments. The circular level can also be seen on a pentaprism located beside the telescope eyepiece.
With an IPX6 rating, the B20-25 has a tough and compact body that is tightly sealed against water, humidity and dust, making it perfect for landscaping, fence building, installing foundation and more.
