More Reliable with 3 Averages: Radon is the second leading cause of lung cancer, INKBIRD radon detector helps us understand the level of indoor radon. We can read three measurements on the screen—long-time average (up to 1 year), last-day average (updated hourly), and last 7-day average.

2-Year Battery Life: This indoor radon detector is battery-operated and will continuously work for up to 2 years on 3 AAA batteries, which are included in the package. Easy to use with low power consumption.

Low Battery Prompt: It has a measurement indicator on the screen, which will blink when the detector is on working status. When the battery power is too low, a low battery prompt will appear. Please NOTE that all data will be deleted after restarting the detector.

Flexible Placement: We can place this radon detector for home, on a flat surface with its foldable stand or hang it on the wall through the hanging hole on its back. It is ideal for any place close to the ground, such as a garage, basement, cellar, and living room, continuously monitoring the radon level in the house.

For accurate measurement, it should be placed 50 cm from the ground and at least 150 cm from the window/door/vent, and not moved during measurement. The measurement data will be displayed after 24 hours of operation, and the average value of 7 days will appear after the detector has worked over 7 days.
