Lower cost sokkia auto level instrument part B2o with ultra-short 20cm focusing

Durable Dependable,

High Value Auto Levels

• 3Models-32x28x,and24x Magnifications
• Rapid,Accurate,and Stable Automatic Compensation
• Ultra-Short 20cm(7.9 in.) Focusing
• All-Weather Dependability
• Clampless,Endless Fine Horizontal Adjustments

Rapid, Stable, and Durable Compensator

The compensator of B20/B30A/B40Aincorporates 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.

All-Weather Dependability
With the lPX6 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 on condensation inside the telescope.

Horizontal Circle for Angle Measurement Horizontal angles can be directly read in 1°or1gon units.Free rotation feature allows you to read any angle from zero.

20cm(7.9in.)- 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.

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 

The B Series has passed operating temperature tests from -20°℃ to + 50°C degree.

Test Durability Test 

The B Series has passed strict durability tests induding rotation of leveling foot screw, Focusing knob and Horizontal fine motor screw.
