Corentium Pro Radon Monitor

The Corentium Pro radon gas monitor is a state-of-the-art measuring instrument that combines ease of use and performance. The Corentium monitor allows you to take a reading of the radon levels and will report daily, weekly and long term concentrations via the app that can be found in your IOS store and Android store.

Corentium Pro 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, and is NRPP certified.

Powered by 3 standard AAA batteries that last up to 2 years. The Corentium monitor is also an essential tool to use when performing property inspections or when checking the operation of a radon mitigation system.

Answer: In the US, a short-term test lasts a minimum of 48 hours. However, we recommend measuring at least 7 days, and preferably a few months. The longer you measure, the more accurate the results.

Question: What is the estimated lifetime of the instrument?
Answer: The estimated lifetime is 10 years. The AA Batteries are estimated to last approximately 2 years.Question: How accurate is the device?Answer: The standard deviation from the exact radon level is less than 7% after 24 hours, and less than 5% after 7 days. Accuracy can be improved further by measuring longer.
