About these items Accurately monitor indoor radon levels with semiconductor or ion chamber sensors. The RM-60 and RM-65 feature a measurement range of 3.3 to 37,000 Bq/m³ (0.09 to 1000 pCi/L) and display results within 6 hours. The RM-73 uses ionization technology for higher accuracy, detecting from 2 to 20,000 Bq/m³ (0.054 to 540 pCi/L) with results in just 10 minutes. All models support tracking over 12 to 96 hours. Designed for simplicity, these radon detectors operate without Wi-Fi or apps. A high-contrast LCD screen displays real-time data and a responsive color bar that shifts with radon levels, giving users visual confirmation at a glance with no setup hassle. All units feature dual alarms for enhanced safety-visual LED alerts and a loud buzzer sound when radon levels exceed limits. Users can customize the alarm threshold to meet local safety regulations or personal preferences. Each model includes a long-lasting rechargeable battery. The RM-60 and RM-65 feature a 2000mAh battery for up to 45 days of standby time and a 3.5-hour full recharge. The RM-73 includes a 5000mAh battery offering up to 12 days of wireless use and recharges in 6 hours. Plug-in use is also supported for continuous monitoring. Compact and easy to place, these radon detectors are suitable for diverse indoor environments-from bedrooms and offices to cars, schools, hotels, bars, kitchens, and campsites. For best performance, use them on a flat, horizontal surface to avoid accidental drops. Key Differences The RM-60 and RM-65 use semiconductor sensors and share similar detection ranges and update cycles. RM-65 has a round, more compact design and weighs slightly more than RM-60, which has a slim rectangular profile. The RM-73 stands out with an ionization chamber sensor for faster and more precise readings, a shorter 10-minute refresh time, a broader design, and a significantly larger battery for higher performance monitoring needs.
