Topcon Automatic Dumpy Level AT-B4 

 

 
 

 

 
Utilizing a finely tuned magnetic damping system, AT-B series automatic levels quickly level and stabilize the line of sight. These precision instruments ensure reliable leveling even when working near heavy equipment or busy highways where fine vibrations could be present. The automatic levels feature IPX6 protection against powerful water jets from all directions and are fully resistant to driving rain and splashing water.
  
Horizontal angles can be directly read in 1 o or 1gon units. Free rotation feature allows you to read any angle from zero. The circle is covered for protection against dirt and scratch. The readout window is located below the eyepiece for quick reading.
 

AT-B Series Features:


Durable, Dependable, High Value Auto Levels
3 Models - 32x, 28x, and 24x 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 AT-B Series 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.  

 

Horizontal Circle for Angle Measurement

Horizontal angles can be directly read in 1 o or 1gon units. Free rotation feature allows you to read any angle from zero. The circle is covered for protection against dirt and scratch. The readout window is located below the eyepiece for quick reading.

 

20cm (7.9 in.) - Ultra-Short Minimum Focus

The AT-B Series can focus on objects at 20cm (7.9 in.) in front of the telescope. This feature dramatically facilitates the works in confined spaces.
