The Topcon AT-B4A optical level, which is the successor to the very popular Topcon AT-B4 model on our market, belongs to the group of instruments with an excellent price-quality ratio. It is one of the most popular and most frequently purchased optical levels in Poland. The instrument is equipped with high-quality optics, protected against fogging and guaranteeing very good image quality. The magnetic compensator enables measurements in unstable areas, where the tripod with the leveler may be exposed to constant vibrations. The instrument is resistant to dust and water (IPX6 standard) and therefore it can be used in harsh conditions - in rain or in a very dusty environment. The leveler is intended, among others for surveyors, road workers, builders, archaeologists - for all specialists who require the highest precision and reliability from a measuring instrument.
the highest precision of measurements - thanks to the excellent Japanese optics (telescope with 24x magnification), the level provides an accuracy of 2.0 mm per 1 km of double-leveling
resistant to hard working conditions, resistant to vibrations and shocks - the built-in magnetic compensator automatically levels the instrument and thus facilitates work in places with unstable and vibrating ground (e.g. on a construction site where heavy machines pass), high standard of water and dust resistance ( IPX6)
at the minimum distance from the staff - the equipment is adapted to work with a minimum target with a length of 0.2 m, which allows you to level the area close to the station without the need to change it
ease of use - the no-range slider of the horizontal wheel allows you to precisely aim the level on the staff, and the circular vial with a mirror enables easy and quick leveling of the instrument
light and small - compact casing and light and durable construction materials make the level possible to be set on a small tripod
stable and reliable - TPI's professional after-sales service ensures that the instrument will operate reliably without any unexpected interruptions
