New Topcon 28x Automatic Level This auction is for four (4) Topcon model AT-B3 28X automatic levels with free shipping. MSRP: $595 USD each. Includes plumb bob, adjusting tools, rain hood, lens cloth, owner's manual, warranty card and carrying case. The units comes new from the factory in individual cardboard store display boxes packed into a single shipping box. 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. Rapid, Accurate, and Stable Automatic Compensation Ultra-Short 20cm (7.9 in.)
