Sokkia B30A Automatic Level

The Sokkia B30A is a versatile automatic optical level designed for everyday surveying, engineering and construction work. It provides a practical balance of optical performance, portability and durability for crews that need a dependable level for regular field operations.

Compared with the high-precision B20, the B30A is positioned as a more general-purpose instrument for construction and engineering applications.

Key Features

• 28× optical telescope for general field surveying

• 1.5mm standard deviation for 1km double-run leveling

• Compact 1.5kg class design

• Quick sighting and easy horizontal adjustment

• Magnetic-damping automatic compensator

• Bright and clear telescope view

• Built-in horizontal circle for basic angle measurement

• IPX6 protection for outdoor field use

Versatile for Surveying, Engineering and Construction

The B30A is intended for survey teams that need one automatic level for a broad range of everyday tasks. Its moderate magnification and lightweight body make it convenient to carry between setups, while the automatic compensator helps maintain an accurate horizontal line of sight.

The instrument is particularly suitable for building construction, roadwork, general engineering surveying and routine elevation checks where the extreme precision of a specialized leveling instrument is not required.
