Carlson CRX

CRx Seamless


The Carlson CRx series of Robotic Total Stations provides a choice of 1″, 2″, 3″ and 5″ angular resolutions to match the application requirements.


The models are recognizable as the CRx-1, CRx-2, CRx-3 and CRx-5, 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 guidance and support for both the robotic total station and SurvCE or SurvPC from one company.

CRx 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.

Advanced Technology
With a 5” touch screen, a more powerful processor for large files, automatic data backup, and the advanced positioning technology of STReAM360, Carlson’s super-reliable CRx robotic total stations provide the most efficient way to survey. 

Made for Carlson SurvCE and SurvPC
Designed to work flawlessly with SurvCE and SurvPC data collection software, the Carlson CRx series robotic total stations are quick to set up, and are packed with easy-to-use functions that simplify your surveying workflows and provide powerful tools to make you more efficient and more accurate.

  • X-MOTION™ Hybrid Drives

  • Scout: Quickly search for passive prisms

  • Full Connectivity

  • Robust, field-proven package

  • accXess™ EDM Technology

  • 1”, 2”, 3”, and 5” options

The CRx Series is also ready for use with the Hybrid+ module for Carlson’s SurvCE or SurvPC field software, which allows the use of your CRx simultaneously with a GNSS receiver such as the Carlson BRx7 to increase your efficiency and accuracy in the field.
