X-Sense XR0A-SR radon detector, LCD averages

The X-Sense XR0A-SR radon detector provides continuous radon monitoring with short-term and long-term average readings on its LCD. Short-term averages cover the past 1, 7, 30 or 90 days, while the long-term reading is cumulative, so no app or laboratory test fee is needed. It starts without configuration and operates silently, with no flashing lights or audible alerts; press once to activate the backlight for viewing in low light. Stored readings are retained during a power interruption, and recording resumes after batteries are replaced; restore power within four hours for data accuracy.
