When first pairing your Wave Plus with your tablet or phone you will see your first measurements appear within 5 minutes. 

While the temperature, air pressure and humidity are ready to go, the TVOC and CO2 sensors will need some time to calibrate, and the radon sensor needs to "learn" about its environment. You can see this from the Airthings App (highlighted in yellow below).

Why do I need 7 days to calibrate the TVOC sensor?


Wave Plus will calibrate itself over these 7 days to get rid of any VOCs that are remaining inside the device as a result of its production and adjust to the new environment.

And what about radon? 

The Wave Plus has a radon sensor which takes hourly recordings of the radon in your environment, and these hourly readings are combined to give you continuous rolling averages. The Wave Plus's radon sensor is designed for long term measurements, so the most reliable result is the long term average. 

7 days is the minimum amount of time we recommend to gather a reliable amount of data, although we advise you to measure for at least 30 days before deciding whether any mitigation action is necessary. The longer you measure for, the more accurate your results will be.

Remember! Temperature, humidity, air pressure, and CO2 are measured every 5 minutes, while radon is measured hourly. :)
