Your guide to X-ray Quality Assurance.

The X-ray testing landscape is undergoing a transformative evolution. To ensure your operations remain future-proof and compliant, it’s crucial to choose solutions that adapt to these advancements seamlessly.

Raysafe Xi – now end of life

RaySafe Xi (also known as Unfors Xi) was discontinued on December 31, 2018 and since December 31, 2023 Raysafe no longer provide service or calibrations.
This means those who still use Xi need to update their system to a more modern solution in order to follow regulations and standards. With the retirement of the RaySafe Xi and the ceasing of its services and calibrations, the time has come for a transition to a more modern solution that aligns with current regulations and standards.

Raysafe X2 – the next Xi?

As the Xi and X2 are completely different meters, the move from one to the other is not inevitable. With the X2 being more than a decade old, this is the time to compare different options.
