Sensors - Orion Air Quality Monitor

The Orion AQM-Gas measures the most common gaseous pollutants nitrogen dioxide (NO2), nitrogen monoxide (NO), carbon monoxide (CO) and ozone (O3), with near-reference measurement performance. Includes the basic meteorological parameters of temperature, humidity, and barometric pressure.

With an enclosure made of anodized aluminum and stainless steel, and a protective rating of IP65, the AQM sensors are built to withstand industrial environments.

Gas Measurement Performance

*90 % confidence interval in comparing with reference instrument, includes T and %RH dependence in typical field conditions and sensor drift during calibration interval. Electrochemical cell replacement interval 12–24 months, depending on local conditions.
