Corentium Plus (US) - QRI

In stock
Featuring multiple state-of-the-art sensors and CRA software, Corentium Plus is designed for radon professionals looking to do more with their data.
Digital system for continuous monitoring of radon gas in indoor air. Download data to PC for analysis and documentation - with the Corentium Report and Analyze (CRA) software. Battery power gives the flexibility of placing the monitor in any location of the building, in order to get a better overview of the radon level in a home, workplace, school or kindergarten.

Corentium plus samples the indoor air through a passive diffusion chamber, and uses alpha spectrometry to precisely calculate the radon level. Detection is done using silicon photo-diodes, both to count and to measure the energy of alpha particles resulting from the decay chain of radon gas. The monitors are calibrated during production, and are not sensitive to changes in temperature, humidity, aerosols and electromagnetic field -, if operated within the recommended operation environment. Battery lifetime under normal operation is more than 18 months.
