Cobia Smart is a simple-to-use instrument for checking that the output from an X-ray tube is correct. Place it beneath the X-ray tube, take an X-ray exposure, and instantly get an accurate reading. The measured values can be read directly from Cobia Smart’s large and clear display, even from a distance. No adjustments are required, making it exceptionally easy to use.
Check and Go
Cobia Smart is perfect for anyone wanting to ensure that an X-ray device is functioning as it should. For example, Cobia Smart is ideal for checking fast and often that the kV and/or dose are not changing over time.
Cobia Smart has a very clear and rotatable color display, so you can read off measurement results fast and easily – even from a distance. The innovative and smart display even shows the results right way up in measurement situations where the instrument needs to be positioned upside down.
Cobia Smart in Different Languages
As well as English, you can choose to run your Cobia Smart 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 we constantly update with more languages.
There are four versions of Cobia Smart for measuring a range of different radiography and fluoroscopy parameters. Select the model that suits your needs, and only pay for what you want to measure.
