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 the 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. 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. Horizontal Circle for Angle Measurement Horizontal angles can be directly read in 1° or 1gon units. Free rotation feature allows you to read any angle from zero. 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 also deters clouding or condensation inside the telescope. TOPCON QUALITY Ultimate Environmental Performance and Durability TOPCON has been performing environmental tests against a set of expected job site conditions to certify the products for long term use. The AT-B Series has been tested by special inspection equipment for complete waterproofness.
