Description
Sokkia B40A-25 / Sokkia 1009572-53
24X Power Automatic Level
The Sokkia B40A-25 24X Automatic Level is a highly accurate
surveying and construction tool for taking a horizontal plane,
height, as well as distance measurements. This optical instrument
features a 24X magnification. To reduce eyestrain, it has an
approximate 1/16 in. accuracy, 0.5 arc-second accuracy and a
built-in compensator that provides exceptionally bright and sharp
views. The B40A-25 comes with an ultra-short focus distance of 7.9
in. from the end of the telescope, making it easy to use in confined
locations. This survey instrument has a 1.26 in. objective aperture,
a quick collimation and a pendulum compensator with a magnetic
dampening system. The 360° horizontal angle measurement can be taken
directly below the eyepiece. With an IPX6 rating, water projected in
powerful jets from any direction have no harmful effects. It
includes a 5/8-11 tripod thread that is compatible with most
tripods. As an extra feature, there is an optional diagonal eyepiece
that can facilitate work in extremely tight spots with little space
behind the instrument.

Freely rotatable circle allows any angle reading from zero.
Right angles can be quickly set for layout and alignment
tasks.
Readout window is conveniently located on the instrument
base directly below eyepiece.
Rapid, Easy Setup
