The measured variables have been configured to AQT530 at the factory.
Gas measurements are updated once a minute. The particle measurement update interval is user-configurable with a default of 10 minutes.
| Measurement | Unit | Update interval | Reported value |
|---|---|---|---|
| Nitrogen dioxide (NO2) | ppb, μg/m3 | 1 minute | |
| Carbon monoxide (CO) | ppb, μg/m3 | ||
| Ozone (O3) | ppb, μg/m3 | ||
| Nitrogen oxide (NO) | ppb, μg/m3 | ||
| Particulate matter PM10 | µg/m3 |
User-configurable Default: 10 minutes |
1-minute average |
| Particulate matter PM2.5 | µg/m3 | ||
| Particulate matter PM1 | µg/m3 | ||
| Air temperature | °C/°F | 1 minute | Instant |
| Air pressure | hPa | ||
| Humidity | %RH |

Stabilization period
The stabilization period is relevant for AQT530 devices that have the gas measurement.
When AQT530 is switched on, let the unit stabilize before using the measurement results. The stabilization time depends on usage conditions, but typically 3 - 5 days in enough to ensure optimal performance.
The units take measurements during the stabilization period, but the measurements from the first 24 hours after power-up are marked as invalid.
