short info

Sokkia B40a Automatic Level feature enhanced reliability under all environmental conditions and are more tightly sealed against water, dust and humidity (IPx6). The B series levels provide quick setup, easy sighting, and superior durability against vibration and shock, ensuring the increased productivity over an extra-long period of time.

The B series Sokkia Auto levels incorporate the most precise and reliable compensator available in the market today. The optimally designed telescope provides exceptionally bright and sharp view that reduces operator’s eye strain. Quick collimation and horizontal angle measurement combine for fast and easy aiming of layout and alignment tasks.

Leveling Accuracy: B20 – ±0.7mm; B30 ±1.5mm; B40 ±2.0mm
Telescope Magnification: B20 – 32x; B30 – 28x; B40 – 24x

Sokkia B40a Automatic Level Description

Rapid, Stable, and Durable Compensator

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

B20/B30A/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 B20/ B30A/B40A withstands a sudden shower or torrential rainfall. The advanced protection design also deters clouding or condensation inside the telescope.
