Automatic Level Waterpass Topcon AT-B2
Product Description
Topcon AT-B2 Automatic Level
Topcon AT-B2 Automatic Level Utilizing a fine-tuned magnetic damping system, the Topcon AT-B2 Automatic Level quickly levels and stabilizes the line of sight. Precision instruments ensure reliable leveling even when working near heavy equipment or busy highways where subtle vibrations may be present. The automatic level features IPX6 protection against powerful water jets from all directions and is fully resistant to heavy rain and splashing water.
Horizontal angles can be directly read in 1 º or 1gon units. The free rotation feature allows you to read any angle from scratch. Closed loop for protection against dirt and scratches. The reading window is located under the eyepiece for quick reading.

Fast, Stable and Durable Compensator
The AT-B Series compensators incorporate four suspension wires made of super-high-tensile metal that has a minimal coefficient of thermal expansion, providing unparalleled durability and accuracy. The fine-tuned magnetic damping system quickly levels and stabilizes the line of sight despite subtle vibrations present when working near heavy equipment or busy highways.
Horizontal Circle for Angle Measurement
Horizontal angles can be directly read in 1 º or 1gon units. The free rotation feature allows you to read any angle from scratch. Closed loop for protection against dirt and scratches. The reading window is located under the eyepiece for quick reading.
20cm (7.9 inch) – Ultra-Short Minimum Focus
The Topcon AT-Series B level can focus on objects at 20cm (7.9 inches) in front of the telescope. This feature dramatically simplifies working in confined spaces.
