The radon sensors in the Corentium Pro are delicate, especially to humid conditions, it is important that storage conditions are non-freezing and non-condensing as well as extreme heat.

We recommend that you keep the Corentium Pro in a dry and low RH environment. Storing the Corentium Pro in a vehicle is not advisable. When the Pro is not in use, it should always be stored in its case.

For storage and doing official radon measurements, remember to stay within the operating environment:

5% Relative Humidity to 85% RH non-condensing

39°F to 104°F / 4°C to 40°C

Failure to follow the recommendations will void warranty.
