When a conductor

electro-magnetic induction
to produce eddy current in
the conductor, and…

AUTOMATIC LEVELS
B20 B30 B40
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.
■ Rapid, Easy Setup
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
can be seen on a pentaprism or plane
mirror located beside the telescope
eyepiece.
■ 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.
■ 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
even faster operation (B20).

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.

■ OM5/OM5F Parallel Plate Micrometer (B20)
To achieve the highest
precision with the top-of-the-
line B20 model, the optional
parallel plate micrometer
OM5 allows for staff readings
in increments of 0.1mm
(estimation to 0.01mm).
Accuracy for 1km double run
leveling can be increased
from 0.7mm to 0.5mm.
Imperial version OM5F has
0.001ft. graduations.

Reticle adjustment is made with one screw. Circular level vial is
adjusted with two screws. Both adjustments are simple and fast with
provided tools.

■ Stadia
The stadia lines on the reticle allow
distance measurements. Simply
multiply the staff length between the
top and bottom stadia lines by 100.
