TopCon AT-B4 Automatic Level

The new affordable AT-B series auto levels offer the well known Topcon precision in a format that can be used on any site. Their ease of use makes them the perfect tool to get started

Big jobs or small, close-in or across the site, Topcons AT-Bs feature a very short focus distance so you can set it up where its the most useful and out of the way

The new Topcon AT-B series levels can focus on objects at 20cm (7.9 in.) in front of the telescope. This feature dramatically facilitates the works in confined spaces.

Fine horizontal knobs located on both sides of instrument can be operated without clamping, speeding up aiming procedures to the staff and other objects.

The AT-B series circular level can be viewed via integrated pentagonal prism (AT-B2) or plane mirror (AT-B3/B4) without changing your eye height.

Horizontal angles can be directly read in 1 degree 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.

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.
