AUTOMATIC LEVEL GOWIN GW-B4

Deskripsi

AUTOMATIC LEVEL GOWIN GW-B4

Automatic Level adalah instrumen optik yang digunakan untuk menetapkan atau memverifikasi titik pada bidang horizontal yang sama dalam proses yang disebut leveling, dan digunakan bersama dengan staf leveling untuk menetapkan level ketinggian relatif dari objek atau tanda. Ini banyak digunakan dalam survei dan konstruksi untuk mengukur perbedaan ketinggian dan untuk mentransfer, mengukur, dan mengatur ketinggian objek atau tanda yang diketahui.

Utilizing a finely tuned magnetic damping system, GW-B series automatic levels quickly level and stabilize the line of sight. These precision instruments ensure reliable leveling even when working near heavy equipment or busy highways where fine vibrations could be present. The automatic levels feature IPX6 protection against powerful water jets from all directions and are fully resistant to driving rain and splashing water.

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.

Gowin GW-B Series Features:

•    Durable, Dependable, High Value Auto Levels
•    3 Models – 32x, 28x, and 24x Magnifications
•    Rapid, Accurate, and Stable Automatic Compensation

Rapid, Stable, and Durable Compensator

The compensator of GW-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 GW-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.
