Topcon AT-B4 24X Auto Level - 60909
Three Finest Models Satisfy ALL Levels of Requirements
Versatile model for surveying, engineering and construction
Economical model for engineering and construction
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 Focus 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.
2-Speed focus (AT B2)
Rotation speed of the focusing knob is automatically switched between coarse and fine, allowing for quick and precise focusing.
Clampless, andless, 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 Vial
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 1Ÿ 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.
Diagonal EyepieceDE16 (AT-B2) / DE22 (AT-B3/B4) Facilitates your works when the level is set at low height or in confined spaces.
Optical Micrometer OM5(F) (AT-B2) Addition of the optical micrometer to the AT-B2 allows for 0.1mm (OM5) or 0.001ft. (OM5F) reading of staffs and improves accuracy to 0.5mm for 1km double run leveling. This combination is ideal for precise leveling.
40x Eyepiece EL5 (AT-B2)Increases magnification of AT-B2 to 40x. Replaces standard eyepiece.
