The Topcon AT-B4A optical level (is the successor of the very popular model on the Topcon AT-B4 market) belongs to the group of instruments with excellent value for money. 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 allows measurements to be made in unstable areas, where a tripod with a level can be exposed to constant vibration. The instrument is resistant to dust and water (IPX6 standard) and thus can be used in harsh conditions - during rain or in a dusty environment. The level is intended for surveyors, road builders, builders, archaeologists - for all specialists who require the highest precision and reliability from a measuring instrument.

Topcon optical levels are known for their high-quality optics. Thanks to it, these instruments allow you to determine the height differences with the highest accuracy. Riflescopes with a magnification of 24x to 32x and a diameter of 32 - 45 mm with an easy-to-use focus adjustment system, provide a sharp and clear image of the patch and thus facilitate accurate aiming and error-free readings. Magnetically damped compensators are responsible for automatic levelling of the instrument's target axis and thus protect users against erroneous readings resulting from inaccurate manual levelling of the level. All Topcon levels are characterized by high resistance to atmospheric conditions, therefore they can be used in virtually any environment. The TPI company checks every new level before selling and rectifies it if necessary. The client receives an instrument certificate confirming the correctness of the device's operation.

  • The highest precision of measurements – thanks to the excellent Japanese optics (telescope with 24x magnification), the level ensures accuracy of 2 mm per 1 km of double levelling,
  • Resistant to harsh operating conditions, resistant to vibration and shock – the built-in magnetic compensator automatically levels the instrument and thus facilitates work in places with unstable and vibrating surfaces (e.g. on a construction site where heavy machinery passes), high water and dustproof standards (IPX6),
  • At a minimum distance from the staff – the equipment is adapted to work with a minimum target of 0.2 m in length, which allows levelling the area close to the station without having to change it,
  • Ease of use – the rangeless horizontal wheel slider allows you to precisely aim the level at the staff, and the vial with the mirror allows easy and quick levelling of the instrument,
  • Light and small – the compact housing and light and durable construction materials mean that the level can be set on a small tripod,
  • Stable and reliable – professional TPI after-sales service ensures the instrument works without any unexpected interruptions.
