Airthings 325 Corentium Home 2 Radon Detector - Bluetooth, Temp

Our review of the Corentium Home 2 finds it best for homeowners and inspectors who want a dependable, always-on radon monitor with clear long- and short-term readouts. The single biggest reason to buy is its combination of the original Corentium accuracy with new Bluetooth connectivity and environmental sensors, which make it easier to track radon trends and correlate spikes to temperature or humidity changes. Setup is straightforward and reading the display is immediate, so anyone concerned about long-term radon exposure will appreciate the practical, continuous data this unit provides.

Key Features

• Original radon sensing: Uses the proven Corentium radon sensing technology to deliver reliable long-term monitoring without the need for lab tests.
• Bluetooth connectivity: Syncs to the Airthings app so users can view interactive graphs and historical radon fluctuations on a phone.
• Temperature and humidity sensors: Built-in environmental readings help correlate radon changes with household conditions for smarter mitigation decisions.
• Clear display with averages: Presents short- and long-term radon averages along with current readings and simple GOOD, FAIR, or POOR indicators for quick interpretation.
• Portable and easy to use: Compact design and simple operation make it suitable for home placement or temporary testing in different rooms.

Who It's For

The Corentium Home 2 is ideal for homeowners who want a trustworthy continuous radon monitor that is easy to read and offers app connectivity for tracking trends over time. It also serves home inspectors and contractors who need a portable instrument to show clients current and averaged radon levels without lab turnaround.

Less suitable for buyers who only need a one-time short-term measurement and do not plan to monitor levels long term, since this device is optimized for ongoing monitoring rather than single-use quick tests. Those requiring multi-device site logging for large buildings should consider professional multi-sensor systems instead.
