Overview for the Topcon AT B4 24X Automatic Level

• With 24x magnification, the Topcon AT B4 Automatic Level ensures precise leveling and angle measurements. This optical instrument features 1/16 inch accuracy and an internal compensator that stabilizes the line of sight despite the fine vibrations caused by heavy equipment, making it perfect for landscaping, fence building, pipe laying, roadwork
• Focus Range: Ideal for surveyors, builders and civil engineers, the AT-B3 has a short focusing range of 7.9 inches in front of the telescope for working in confined spaces. With a stable and durable magnetic dampened compensator, this survey and construction tool levels the line of site within the range of ±15 arc-minutes and an accuracy of 0.5 arc-second.
• Endless Fine Horizontal Adjustments: The fine horizontal knobs located on both sides of this Topcon auto level can be operated without clamping, speeding up aiming procedures to the staff and other objects. In addition to height and angle, distance to the staff can also be measured by simply reading the length of staff between two stadia lines and multiplying the value by 100.
• Horizontal Circle: Protected against dirt and scratch, the horizontal circle features free rotation that enables you to read any angle from zero. Horizontal angles can be directly read in degrees or gons and the readout window is located just below the eyepiece. The ATB3 also allows you to easily view the circular level through its integrated plane mirror without changing your eye height.
• Water Resistant: The AT-B4 features IPX6 protection against powerful water jets from all directions and is fully resistant to driving rain and splashing water. This advanced protection design not only prevents water from entering the instrument, but also deters clouding or condensation inside the telescope.
• This Topcon automatic level comes with a hard carrying case, plumb bob, hex wrench, adjusting pins, vinyl cover, cleaning cloth, lens cap and 5-year manufacturer’s warranty.
