OVERVIEW
TEKNİK ÖZELLİKLER
Using a finely tuned magnetic damping system, AT-B auto levels quickly straighten and stabilize the line of sight. These precision tools provide reliable balancing even when working near heavy equipment or near busy highways where subtle vibrations can occur. Automatic levels have IPX6 protection against powerful all-round water jets and are fully resistant to rain and splashing water.
Horizontal angles can be read directly in 1º or 1gon units. Free rotation feature allows you to read any angle from scratch. The circle is covered for protection against dirt and scratches. Reading window is located under the lens for fast reading.
