Carlson CR+ Series Robotic Total Station

Carlson CR+ Series Robotic total stations

The Carlson CR+ series of Robotic Total Stations provides a choice of 1″, 2″ and 5″ angular resolutions to match the application requirements.

The models are recognizable as the CR1+, CR2+ and CR5+, and all feature the same technologies for a seamless user experience. The instruments are combined with SurvCE or SurvPC on a field computer to access the full range of Carlson survey features for efficiency and automation in a familiar environment. In addition, users have the option for installing SurvCE Basic on board for operation with the instrument only. Customers benefit from technical support for both the robotic total station and SurvCE or SurvPC from one company.

The experienced technical support team provides guidance and instruction for using the instrument and Carlson software for many applications such with surveying, engineering and construction.

CR+ Robotic Total Stations are used with SurvCE or SurvPC in a wide range of applications requiring precise angle and distance measurements such as surveying, engineering and construction.
