Auto Level Sokkia B40A Survey Level with High Accuracy Measuring Instrument
Hot Brand Sokkia Automatic Level B40A with High Quality
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.
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 knobs of endless horizontal motion drives can be operated with either hand for fast and
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.
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.
