Which parameters can TERA Environnement’s connected stations measure?

For indoor air, the stations measure CO2 (0-5000 ppm, NDIR method), PM1, PM2.5 and PM10 particulate matter (0-1000 µg/m3), total VOCs by PID photoionization (0-50 ppm), NO2 (0-20 ppm), O3 (0-20 ppm), and optionally formaldehyde or CO. For ambient air, they mainly measure PM1, PM2.5 and PM10 and total VOCs, with options for CO, NO2, H2S and NH3. All stations continuously measure temperature and humidity.
