Series 900 – Fixed Air Quality Monitor
The Series 900 Fixed Air Quality Monitor is a flexible monitor designed to streamline real-time measurement of multiple gas pollutants. Available in three primary configurations, optimized for indoor air quality monitoring, ozone monitoring, or monitoring of Volatile Organic Compounds (VOCs). Suitable for use on a range of projects, including occupational health and safety monitoring, indoor air quality monitoring, industrial process control, and leak detection.
Gas pollutants
NH3, CO, CO2, Cl2, CH2O, H2, CH4, H2S, NO2, O3, C2Cl4, SO2, NMHCs, VOCs
Environmental factors
Temperature, humidity
The Series 900 Fixed Air Quality Monitor is used by environmental health and safety (EHS) managers, employers, and air quality professionals of all types to ensure sensitive receptors are not at risk of overexposure to harmful gas pollutants, including ozone and VOCs.
Key technology of the AQS 1
Active fan sampling
Aeroqual’s sensor heads use active fan sampling to draw sample air to the sensor, capturing highly accurate measurements.
Swappable sensor head technology
Easily swap gas sensor heads in seconds with no configuration or recalibration required.
Analog and digital outputs
Includes a 4-20 mA analog output to connect to a PLC or current sensing device, and RS485 digital output for logging data to a central point.
Free software download
Free configuration and networking software allows for easy configuration of alarm and control set points, along with logging of network data to a single PC.
Key benefits
Measure a wide range of pollutants
A swappable sensor head design makes it easy to switch between modules, with all available Aeroqual gas modules supported, including four ranges of ozone and VOC sensors.
Flexible applications
Use as part of a monitoring network, a gas transmitter, or as a relay controller for an external device.
Portable design
The Series 900 is lightweight, discrete, and easily wall mountable, streamlining installation in any environment, with an operating range of 0°C to 40°C.

Series 900 Fixed Monitor
The Series 900 is a base unit and does not have an enclosure.
Series 930 Fixed Monitor
The Series 930 enclosure is Polycarbonate/ IP41* NEMA 2** equivalent.
*IP 41 Rating: Protected from tools and small wires greater than 1 millimeter. Protected from condensation.
**NEMA 2: Indoor use to provide a degree of protection against a limited amount of falling water and dirt.
How do I calibrate my Fixed Monitor sensor heads?
We recommend that sensor heads be calibrated at least once a year.
Series 900 Fixed Monitor – Type 1 Sensor Head
Factory calibration. Return sensors to Aeroqual for a multi-point calibration and new calibration certificate. Please contact our support team.
Manual calibration. Gas sensors only. Please refer to our page on portable monitor calibration.
Series 930 Fixed Monitor – Type 2 Sensor Head
Factory calibration. Return sensors to Aeroqual for a multi-point calibration and new calibration certificate. Please contact our support team.
What are the different output types?
Series 900 and Series 930 Fixed Monitor
Analogue output: 4-20mA (opto-isolated), 12-24V
Digital output: RS232 and RS485
Can I use the Series 900 Fixed Monitor with my own software?
The user guide for each of the Fixed Air Monitors contains the relevant protocol commands for integrations into third-party systems. User guides can be found on the Technical Documents page.
