The Topcon AT B2 Automatic Level supports surveyors and construction professional to achieve accurate and reliable readings. This product was designed to deliver precision in leveling, angle, height, and distance measurements. This optical instrument is equipped with a 32x magnification and a 1/32 inch accuracy. Its design includes a built-in compensator to counteract the minute vibrations often encountered on busy job sites, ensuring a stable line of sight under all conditions.
Key Features
Advanced Focus Range for Versatile Applications: The AT B2 showcases a minimum focusing range of just 7.9 inches, enabling functionality even in the tightest spaces. Its internal magnetic dampened compensator provides the leveling of the line of sight within ±15 arc-minutes with an accuracy of 0.3 arc-second, making it a versatile tool for detailed surveying and construction tasks.
Operation with 2-Speed Focusing Knob: The AT B2 features a 2-speed focusing knob that automatically adjusts between coarse and fine focusing, allowing for swift and accurate adjustments. Dual fine horizontal knobs, accessible from both sides of the instrument, enable quicker aiming without the need for clamping, streamlining the measurement process.
Reliable Horizontal Circle and Angle Measurement: Equipped with a protected horizontal circle, the AT B2 allows for direct reading of degrees or gon right below the eyepiece. Its design protects against dirt and scratches, while the free rotation feature facilitates easy angle reading from any starting point.
Water Resistance for Field Durability: Rated at IPx6, the AT B2 can be used in wet conditions. This means that surveyors do not need to fear their projects being affected by weather conditions.
What's Included: Included with the AT B2 is a hard carrying case, plumb bob, hex wrench, adjusting pins, vinyl cover, cleaning cloth, lens cap, and a 5-year manufacturer’s warranty.
