Automatic Level Sokkia B40A
Product Description
The compensator of B20/B30A/B40A incorporates four suspension wires made of super-high-tensile metal that features minimal thermal expansion coefficient, providing unmatched durability and accuracy. Finely tuned magnetic damping system quickly levels and stabilizes the line of sight despite the fine vibrations present when working near heavy equipment or busy roadways.
20cm (7.9 in.) – Ultra-Short Minimum Focus
B40A can focus on objects at 20cm (7.9 in.) in front of the telescope. This feature dramatically facilitates the works in confined spaces.
Horizontal Circle for Angle Measurement
Horizontal angles can be directly read in 1° or 1gon
units. Free rotation feature allows you to read any angle
from zero.
All-Weather Dependability
With the IPX6 rating, the instrument is protected against powerful water jets from all directions, meaning B40A withstands a sudden shower or torrential rainfall. The advanced protection design also deters clouding or condensation inside the telescope.
