Quality Assurance Meter Provides Streamlined X-Ray Constancy Checks

A quality assurance (QA) meter provides an effective and convenient way to make the regular constancy checks of X-ray equipment as fast and as accurate as possible.

Cobia Sense, developed by RTI Electronics (Mölndal, Sweden), is designed for use with an external detector such as RTI dose probe, light probe, computed tomography (CT) ion chamber, or external mAs probes. The wide selection of external probes enables a big flexibility in the performance of regular constancy checks for most modalities. The measured values can be read directly from the large and clear display, and are stored in the Cobia Sense for later viewing.


As the newest product in the Cobia range, the Cobia Sense has the same form factor and large display, which features the Cobia’s easy-to-navigate menu structure. The Cobia Sense is designed for routine constancy checks, with the goal to make those tasks fast and easy.

Due to the Plug-and-Play functionality, the technology will automatically recognize the different detectors that are connected and instantly be ready for measuring. This, combined with the easy-to-read display, also makes the device a suitable tool for untrained users.

Using the meter, there is no need to reset between measurements; therefore, the user can remain in the control room until all the measurements are made. The practical data log stores measurements for later viewing.

As well as English, one can choose to run Cobia Sense in several languages such as Chinese, French, German, Japanese, Norwegian, Russian, Spanish, Swedish, and Turkish. This can easily be selected via the Cobia menu and the company constantly updates with more languages.
