Corentium Plus samples indoor air through a passive diffusion chamber, using alpha spectrometry to precisely calculate the radon level. Radon is detected using silicon photodiodes to both count and measure the energy of alpha particles resulting from the decay chain of radon gas. The instrument is calibrated to reference instruments in accredited laboratories.
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 extensive, including the ability to generate custom graphics, custom professional reports, and convert all the data into a CSV file.
Question: How often does the device need to be calibrated and how much does it cost to calibrate?
Answer: There is no need to calibrate the Corentium Plus over its lifetime. The device comes pre-calibrated and adapts automatically to its new environment to provide accurate readings.
Question: How quickly can the Corentium device calculate accurate results? A home inspection lasts only a few hours, will it have to be left overnight?
Answer: To integrate daily variation of radon concentration, a short-term test should last a minimum 48 hours. However, we recommend measuring for at least 5 to 7 days if it’s possible, and preferably a few months. The longer you measure, the better the accuracy.
Question: What is the estimated lifetime of the instrument?
Answer: The estimated lifetime is 10 years. The AAA batteries are estimated to last approximately two years.
