Choose the measurement method first, then the features you need.
A suitable test kit can be a sensible first purchase. Check its procedure and lab arrangements; local radon programs may offer testing options. Compare kits and monitors.
Check the intended test location, operating conditions and power arrangement. A regularly occupied basement and an unused storage area can call for different placement decisions. Read the basement setup guide.
Choose a model with a documented radon sensor. Home 2, View Plus and RD200 all include radon measurement. Understand the sensor differences.
