DIGITAL RADON MONITOR - Airthings Corentium Plus

• Professional radon gas monitor of great accuracy.

• You can view and record the daily average weekly and annual cumulative value.

 

DESCRIPTION

 

• The Corentium Plus is a sophisticated, convenient and powerful monitor designed to provide accurate and detailed data for a thorough analysis of radon concentration. It continuously records radon concentrations in 1-hour cycles, allowing users to download all measurement data to a PC for detailed analysis.

• The Corentium Plus is additionally equipped with sensors for air pressure, temperature and humidity, the measurement data of which are also continuously recorded and can be downloaded and transferred to other applications.

• Built with multiple state-of-the-art sensors, the Corentium Plus will record everything needed to fully understand fluctuations in radon concentration.

• The Corentium Report and Analyze (CRA) software, which comes with the Corentium Plus, allows the user to download all the data from the monitor and each sensor to a PC. The software functionalities are seemingly endless, including the key features of generating custom graphics, custom professional reports and converting all the data into a csv-file (Excel document).

• Corentium Plus samples indoor air through a passive diffusion chamber, and then uses alpha spectrometry to precisely calculate the radon level. Detection is done using silicon photo-diodes to both count and measure the energy of alpha particles resulting from the decay chain of radon gas. The battery lifetime under normal operation is approximately 18 months.
