The RTI Black Piranha X-ray QA meter

The Black Piranha X-ray QA meter is a self-contained, multi-functional meter for all X-ray based QA applications, providing easy and fast X-ray quality control.

The Piranha along with its range of accessories makes X-ray QA easy and fast. The connection is automatic – just plug n play. The Quick Check feature identifies the probes you insert and selects the optimum Piranha settings for your measurements – sit back and let the Piranha do the work!

An easy and fast X-ray QA meter

Everything happens in a flash! The Piranha X-ray QA meter makes quick measurements and with its Ocean software your daily QA-work will go quickly. Ocean can perform instant real-time analysis during your measurements. Ocean also prepares a report in the background as you go. So when the work is done, if you want a complete report of your work – just press print.

Use your tablet/laptop as both an interactive display during the measurements and as a powerful analysis tool when you are back at the office. All your measurements, along with the result and the report will be stored inside your tablet or laptop. No unnecessary, time-consuming data-transfer at the end of the day.

Easily store your X-ray QA meter data

During the measurements, you will only see the desired values on your tablet or laptop but since the Piranha continues to work behind the scenes, you always have access to all of the data from each measurement. This enables you to perform for instance trend analysis and study the history of each X-ray equipment – even months after you have completed your measurements.

A complete X-ray QA solution

The Piranha comes ready-to-use with everything you need included. It is really an all-in-one multifunction meter. Connect to your computer wireless or via USB and you have a complete QA-system! The number of Piranha models available ensures that you only pay for what you need. As your needs grow, you have unlimited ability to upgrade your Piranha.

Piranha has a unique feature that makes it possible to check the position of the detector before measuring. By using the “Position Check” function, you can verify that the detector area is fully irradiated. Possible field inhomogeneities are also neutralized.
