Sokkia B40A-25 Automatic Level 24 power 1009572-53

Product 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.

Sokkia B40A-25 Automatic Level KEY FEATURES

Superior Telescope

Optimally designed telescope provides exceptionally bright and sharp view that reduces operator's eye strain.
Ultra-short focus distance of 20 cm from end of telescope makes it easy 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.
Readout window is conveniently located on the instrument base directly below eyepiece.

Rapid, Easy Setup

A domed-head tripod makes setting up faster and easier even on on inclined and uneven ground
The B-Series levels also fit flat head tripods.
The circle level can be seen on a pentaprism or plane mirror located beside the telescope eyepiece.
