The Cobia SMART offers the simplest solution for checking that the output from an X-ray tube is correct for a range of different modalities including radiography and fluoroscopy.

Cobia Smart is a straightforward and simple-to-use instrument for checking that the output from an X-ray tube is correct. Place it beneath the X-ray tube, make an X-ray exposure, and rapidly 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.

Rotatable Color Display

Cobia Smart has a clear and rotatable color display, so you can read off measurement results fast and easily – even from a distance. The innovative display even shows the results right way up in measurement situations where the instrument needs to be positioned upside down.

Straightforward and Trouble-free

When we created the Cobia Smart, our goal was to develop a straightforward instrument that anyone could use. RTI has over 30 years of experience in the manufacture of X-ray detectors, and Cobia Smart is a direct implementation of our high-tech knowledge coupled with what we have learned in the field.
