The Topcon AT-B Series Automatic Level has been upgraded to present a smaller lightweight design while still enhancing the features of the unit. It enables surveyors and construction professionals to perform highly accurate leveling, angle, height, and distance measurements. Offering a minimum focus range of up to one feet, this auto level also has a leveling accuracy of up to ±1/16 inches making it a perfect choice for engineering and construction works.

This AT-B-Series automatic level retains its superior optics and promotes better visibility of a 1-degree (1 gon) horizontal circle. With a stable and durable magnetic dampened compensator, this surveying and construction tool levels the line of site within the range of ±15 arc minutes and an accuracy of 0.5 arc-second. Additionally, it is designed with improved tangents and knobs, while its increased gear ratio allows it to withstand shock and vibration.

This Topcon auto level employs the same durable, fast and reliable compensator, only made compact for easier grasp. With an IPX6 rating, this survey instrument is protected against dust, water, and humidity.

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. 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.

Horizontal Circle for Angle Measurement

Horizontal angles can be directly read in 1º or 1gon units. Free rotation feature 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.

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.
