The Cobia FLEX offers you the flexibility to connect different external probes and ion chambers, with the option of built-in mAs.

The Cobia Flex offers the same ease of use as the Cobia Smart, but with more possibilities, making X-ray quality assurance procedures as quick and accurate as possible.

Easy to use with more possibilities

A straightforward and simple to use instrument, the Cobia Flex is able to connect to external probes and ion chambers via the ion chamber adapter as well as the usual built-in MAS and internal detector, producing a system that is accurate, inexpensive and easy to use. Simply expose either the external probes or the internal detector to the X-ray source and the output of the X-ray tube is displayed on the crystal clear display or can be stored in the instrument and read after all your measurements are complete. If both the internal detector and an external probe are exposed, the Cobia Flex can even detect which X-ray source is most likely to be the required measurement by comparing dose and displaying the highest. Alternatively, both can be viewed.
