Radon Detectors for Home, Radon Monitor with 12H Initial Result

• RELIABLE & ACCURATE DETECTION: The METRINARY radon monitor uses a high-precision semiconductor sensor with a wide detection range of 0.09–1000 pCi/L (3.3 Bq/m³–37 kBq/m³). The first stable reading is available after 12 hours, with hourly updates thereafter. It would help you make informed decisions about your home environment.
• LONG-TERM DATA STORAGE & TREND ANALYSIS: Automatically records radon levels every hour and stores up to 504 days of historical data. View 24h, 48h, 72h, 96h averages, cumulative averages, and peak levels. Perfect for monitoring seasonal radon fluctuations in basements, crawl spaces, or living areas.

When radon concentration exceeds your preset limit, the device triggers both flashing red visual alerts and audible beeps, ensuring you never miss elevated radon levels in your home, basement, or workplace.
