Surveying and Engineering Automatic Levels

Topcon' s engineering and construction automatic levels are streamlined and more compact than ever. They are lightweight for easy transport and the completely waterproof telescope is effective for all kinds of wet surveying operations.

Angular reading to 10 minutes ( AT-G1)

Model AT-G1 has a glass horizontal circle which is graduated in 10 minute divisions ( 10c divisions) and numbered every degree ( one grade) with calibrations from 0° to 360° ( 0g to 400g) . Furthermore, readings are possible through a 25x reading microscope, with only a slight shift of the eye, from the telescope eyepiece. The horizontal circle freely rotates for zero alignment.

Waterproof sealed telescope construction

The instrument has a completely waterproof telescope and is therefore ideal for all kinds of wet-surveying operations, in light rain or in tunnels. Only test-approved telescopes are used and dry nitrogen gas is sealed in the telescope tube. This effectively prevents lens clouding and moisture condensation.

2 speed focusing ( AT-G1)

Fine and coarse focusing is provided by a coaxial focusing knob, which permits rapid setting and accurate focusing for perfect image at the same time.

Clamp less fine horizontal adjustments

Fine horizontal adjustments are possible at any point through 360° ( 400g) of the arc, without clamping action. This means that target alignments are greatly speeded up. Furthermore, fine horizontal knobs are available on both sides for very easy and speedy adjustments.

Very short 0.5 meter focusing ( AT-G3/ G4/ G7N)
AT-G3/ G4/ G7N have a short range setting position of 0.5 meter that is especially suitable for close range work carried out by builders and contractors.

Rapid, stable automatic leveling

A time-proven magnetically damped compensator is incorporated for automatic leveling action. It is not affected by fine vibrations and has been proven to have very stable precision, thus speeding up automatic leveling operations and producing accurate results. The Topcon-exclusive automatic leveling system utilizes four special mylar ribbons for hanging the magnetic damper compensator. The compensator is therefore not influenced by the magnetic field, as well as having superior resistance to cold, heat and shock.

Rubber eyepiece cap

Sighting through Topcon' s AT-G7 is safe for anyone who wears eyeglasses. With their protective rubber eyepiece caps, scratches and abrasions are reduced or eliminated completely.
