Topcon offers a wide range of automatic levels for the land surveyor, civil engineer and contractor. All AT-G series levels feature a magnetically-dampened compensator hung by four special mylar ribbons having superior resistance to cold, heat and shock. The AT-G1 model features a 360° glass horizontal circle using a 25x magnification microscope to read the circle, while the AT-G2 thru AT-G7 have a standard 360° horizontal circle. All models are waterproof with a nitrogen gas sealed telescope which prevents clouding and moisture on the lens.
