Quick and accurate Quality Control

For Rad/Fluoro as well as Intraoral and CBCT measurements, RTI Cobia FLEX R/F offers you the convenience to make your X-ray Quality Control as quick and accurate as possible.

It is just as easy as the Cobia SMART, but with even more possibilities to help you determine patient safety every day.


Large and clear display

The measured values can be read directly from the large and clear display and stored in the RTI Cobia FLEX R/F to read later.

The meter not only has an internal detector but a detector input that offers the ability to connect different probes and ion chambers. There is also optional built-in mAs.

Ocean Next™ software

Our Ocean Next™ software exhibits Cobia’s capabilities and adds benefits that make the workflow more practical and simpler. The software makes it possible to perform remote X-ray testing and QA measurements with your Cobia Flex R/F. You simply connect to your Cobia with a USB cable to your PC or Tablet, and then measure!

With the addition of Ocean Next™ Professional, the Cobia FLEX R/F becomes an indispensable solution for data management, efficiency, time-saving procedures, and compliance.
