Product Description
SOKKIA B40A optical level automatic leveling level
B40A compensator adopts magnetic damping system, the surrounding environment produces small vibration, quickly calm the instrument and ensure the stable line of sight; ultra-short visual range of 20cm, bring great convenience in the narrow space environment. IPX 6 high protection level can withstand strong splashing water in any direction, and is suitable for harsh working environment in the field.
Durable, reliable, and cost-effective
Three models and three magnifications (32x, 28x, and 24x)
Fast, accurate, and stable automatic compensation
20cm ultra short focal length
24/7 high reliability operation
Unlimited horizontal fine-tuning
Fast, stable, and durable compensator
The four suspension wires used in the B20/B30A/B40A compensator are made of ultra tensile metal with low thermal expansion coefficient, providing unparalleled durability and measurement accuracy; Even small vibrations caused by nearby heavy construction equipment or busy traffic, a good magnetic damping system can quickly level the instrument and ensure stable visibility.
Ultra short focal length
B20/B30A/B40A can focus on targets only 20cm away from the telescope, bringing great convenience to operations in narrow space environments.
Horizontal dial
The horizontal dial adopts a 1 ° marking and can rotate freely to zero the reference direction and directly read the horizontal angle value in any direction.
24/7 high reliability
The IPX6 high protection level of B20/B30A/B40A can withstand strong splash in any direction, which means that sudden shower or rainstorm will not affect the instrument; Advanced protective design can also prevent the generation of stains or condensation inside the telescope.

SOKKIA Quality
A model of performance and durability
Through various expected operating conditions and the use of specialized testing equipment to conduct temperature, humidity, vibration, and drop tests on the product, the excellent performance of the SOKKIA B series automatic leveling instrument, such as waterproofing and durability, has been fully verified and has a good reputation for a long time.
Waterproof performance test
The B series has passed the test of withstanding strong jet water flow in all directions, and no equipment has entered the machine.
High and low temperature environment testing
The B series has passed tests for normal operation in temperature environments ranging from -20 ° C to+50 ° C.
Durability testing
The B series has passed rigorous durability tests on components such as foot screws, focusing handwheels, and horizontal adjustment screws.
