Sokkia iM 55 Total Station
Compact Sokkia IM‑55 total station for everyday construction layout and topographic surveying tasks.
Standard finish in stock. Custom fabrication adds 5 days.
The Sokkia B40A automatic level incorporates field-proven precise and reliable compensators for accuracy you can rely upon. The optimally designed telescope provides an exceptionally bright and sharp view that reduces the operator’s eye strain. Quick collimation and horizontal angle measurement combine for fast and easy aiming of layout and alignment tasks.
SOKKIA has been performing environmental tests against a set of expected job site conditions to certify the products for long term use. The B Series has been tested by special inspection equipment for complete waterproofness. The B Series also has the highest environmental performance and durability in SOKKIA’s Auto Level history, proven by tests against temperature, humidity, vibration, and drop.
Water Proof Test (IPX6)
The B Series is proven to withstand powerful water jets from all directions without any submergence inside the unit.
Cold and Heat Resistance Test
The B Series has passed operating temperature tests from -20 to +50 degrees.
Durability Test
The B Series has passed strict durability tests including rotation of the leveling foot screw, Focusing knob, and Horizontal fine motor screw.
Rapid, Stable, and Durable Compensator
The compensator of the Sokkia B40A Optical Level 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
Sokkia Auto Level 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. The 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 Sokkia Level B40A withstands a sudden shower or torrential rainfall.
The advanced protection design also deters clouding or condensation inside the telescope.
