The Topcon AT-B series sets a new standard for auto levels used in surveying, engineering and construction applications. The AT-B4A automatic level features further enhanced reliability under all environmental conditions. With the IPx6 rating, the instrument is protected against powerful water jets from all directions, making it fully resistant to driving rain and splashing water. The Topcon AT-B4A quickly levels and stabilizes the line of sight with its finely tuned magnetic damping system, in spite of any fine vibrations present when working near heavy equipment or busy highways.
