As compact and flexible as X-ray QA can get

Quick and accurate Quality Control
For Rad/Fluoro as well as Intraoral and CBCT measurements, the 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 to determine patient safety every day.

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

Cobia FLEX R/F users also have the possibility to use a PC or Tablet, save data to a computer, print reports, use analyses, and much more.


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 QA measurements with your Cobia Flex R/F. You simply connect to your Cobia, via Bluetooth, or with a USB cable to your PC or Tablet, then measure!

With the addition of Ocean Next™ Professional, the Cobia FLEX R/F truly becomes an indispensable X-ray QA tool – offering a complete system for superior efficiency and compliance. Perform your QA work – be it sensitivity, kV ranges, or waveform types – automatically and without any worries.
