Wave can display radon levels in both pCi/L or Bq/m3.
The device automatically displays pCi/L if you are in the United States. For all other countries, it will automatically display the radon levels in Bq/m3
You are able to change these settings within the mobile application to suit your specific needs. All you have to do is go to the hamburger menu on the top left side and open Settings, from here you can change your measurement units from Metric to Imperial or vice versa.
