For most users, simply turning on the AQY 1 is enough - data will start flowing. The AQY 1 comes factory calibrated and will report measured air quality parameters accurately.
For some users, with high-data quality objectives, calibration against a ‘reference’ station is the best way to ensure highest correlation between AQY 1 and reference.
This section describes how to perform a calibration of an AQY 1 using the method of co-location with a regulatory monitoring station. The AQY 1 contains both gas (O3, NO2) and particulate matter (PM2.5) sensors. Calibration via co-location provides a robust method of calibration that works for all measurements.
AQY 1 calibration is recommended when inter-comparability with regulatory monitoring data is required. It’s often performed before and after deployment for project-based work or at regular intervals in long-term monitoring projects.
Co-location calibration compares data (usually hourly averaged) from the AQY 1 with the regulatory data and uses linear regression to calculate new slope and intercepts. These are then input into the AQY 1 via the Calibration and Service app in Aeroqual Cloud or Aeroqual Connect.
