TOPCON AT B3 Automatic Level

There are three models available in the AT-B line up: the AT-B2, AT-B3 and AT-B4 models, all of which share a common IPX6 environmental rating. 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.
