Topcon AT-B2 32x Long Range Automatic Level

Description

Topcon 32x Automatic Level
Topcon model AT-B2 Long Range 32X automatic level is Topcon's longest range optical level for precision elevation control.  Includes plumb bob, adjusting tools, rain hood, lens cloth, owner's manual, warranty card and carrying case. The unit comes new-in-box from the factory with a Five (5) year warranty.
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 even in the harshest environmental conditions. 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 Focusing Range
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.
Focus
Clampless, Endless Fine Horizontal Adjustments
Fine horizontal knobs located on both sides of instrument can be operated without clamping, speeding up aiming procedures to the staff and other objects.
Easy-to-See Circular Level
Circular level can be viewed via integrated pentagonal prism (AT-B2) or plane mirror (AT-B3/B4) without changing your eye height.
Horizontal Circle for Angle Measurement
Horizontal angles can be directly read in 1u00b0 or 1gon units. Free rotation feature of the horizontal circle 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.
All-Weather Dependability
With the IPx6 rating, the instrument is protected against powerful water jets from all directions, meaning the AT-B series withstands a sudden shower or torrential rainfall. The advanced protection design not only prevents water penetration, but also deters clouding or condensation inside the telescope.
Distance, Angle, and Height Measurement
In addition to height and angle, distance to the staff can be simultaneously measured using stadia lines. This is accomplished by reading the length of staff between two stadia lines and multiplying the value by 100.
