The Corentium Home by Airthings radon detector is a portable, lightweight radon measuring instrument that combines ease of use and accuracy. What is Radon? Radon is a naturally occurring, radioactive gas that comes up from the ground and can accumulate to unsafe levels in the home. It is odorless, colorless and tasteless. Radon gas is in the air all around us and levels fluctuate daily. The good news is that a digital radon detector warns you when levels are getting high. Powered by 3 standard AAA batteries, the Corentium Home LCD digital display shows the first indication of your radon levels within 24 hours. Unlike radon test kits, there’s nothing to send to a lab and no shipping fees. The Corentium Home radon gas detector displays daily, weekly and long term average radon levels allowing you to take action if there are unsafe levels of radon gas in your home. The Home Radon monitor is an essential tool to use when buying a house or selling a house and it also ensures a radon mitigation system is performing properly. Airthings devices have superior sensors to ensure that you can have a healthy home and breathe in clean air. The internal architecture of the Home radon monitor comes from advanced technology normally reserved for professional-grade detectors. Developed by particle physicists, our state-of-the-art radon testing sensor is incredibly accurate and requires no annual calibrations throughout its useful life, estimated at over 10 years.
