The Cobia DENTAL is a simple-to-use instrument for checking that the output from Dental Intraoral X-ray tube is correct.

Since the Cobia is easy to position and does not require any complicated settings, anyone who works in the dental clinic can quickly and easily perform the routine inspection of the intraoral X-ray equipment.

Check and Go

The Cobia Dental is especially suitable for acceptance test, constancy test, and routine quality control of Intraoral X-rays. The basic need for a dental clinics calibration check of kV and exposure time is covered with the standard kV model of Cobia Dental. With a small addition to price, dose and HVL measuring will also be included.

Ease of Use

Cobia Dental is designed for “ease of use” which is accomplished through easy positioning and possibilities to choose your preferred language together with a powerful and clear color display. The screen is rotatable and is easy to read from a distance, and your 100 latest measurements will always be automatically saved.

For Everyone

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

Rotatable Color Display

Cobia Dental 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.

Only Pay for What You Need
