Cobia Dental

A simple-to-use instrument for routine inspection of Intraoral and CBCT X-ray equipment in dental clinics. Especially suitable for acceptance test, constancy test, and routine quality control.

Cobia Dental - for fast and easy intraoral and CBCT system testing

Cobia Dental has rapidly risen in popularity among dental engineers, physicists, and managers all over the world.

The Cobia Dental solution is the first choice for fast and easy Intraoral and CBCT system testing, service, and maintenance in a compact and lightweight portable kit. Measurements are displayed directly on the integrated screen and transmitted wireless straight to your Ocean software for easy storage and analysis.

Cobia Dental is a simple-to-use meter for checking that the output from Dental Intraoral X-ray tube is correct. Since the Cobia is so easy to position and doesn’t 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. To determine patient safety – every day.

Everyday “check ups”

The Cobia Dental is especially suitable for acceptance tests, constancy tests, and routine quality control of Intraoral X-rays. The basic need for a dental clinic calibration check of kV and exposure time is covered with the standard kV model of Cobia Dental. With a small addition to price, dose, total filtration 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.

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.

Cobia Dental in different languages

As well as English, you can choose to run Cobia Smart in several languages such as Chinese, French, German, Indonesian, Japanese, Norwegian, Polish, Portuguese, Russian, Spanish, Swedish, and Turkish. These can easily be selected via the Cobia menu, and we constantly update with more languages.
