Patented Innovative Radon Calibration Chamber Technology

Ready to establish your radon calibration laboratory with a state-of-the-art, fully automated solution, designed to ensure reliability, simplify setup, and support your path to accreditation?

In response to the long-standing lack of cost-effective calibration services across Italy and Europe, I began developing a novel radon calibration chamber concept in 2018. The goal: to offer laboratories and manufacturers a high-performance, flexible, and standards-compliant system at a fraction of the typical cost.

After years of research, testing, and collaboration with radon professionals, this vision became reality culminating in a patented system featuring:

  • HYBRID MODE: A unique operating method that ensures precise control of radon activity concentration in the chamber, enabling smooth, accurate adjustments.
  • Automated Control System: Built around a microcontroller on a custom PCB, programmed in C++, capable of managing pumps and valves to perform fully automated calibration cycles.
  • Efficient Exhaust System: Reduces downtime, enhances safety, and accelerates processing.
  • Standards Compliance: Designed in accordance with IEC 61577-4:2009, ensuring compatibility with international radon calibration protocols.

Following the construction of a functional prototype in 2021 and real-world testing of the finalized system, I’ve now launched an updated version of the control unit more robust, versatile, and ready for market deployment.

This technology is ideal for:

  • National laboratories

  • Commercial calibration centers

  • Radon device manufacturers

Take advantage of this patented, ready-to-integrate solution and bring your radon calibration capabilities to the next level.
