Series 900 – Fixed Indoor Air Quality Monitor
The Series 900 Fixed Indoor Air Quality Monitor is a flexible monitor designed to measure and control gas concentrations in air. Compatible with a range of swappable gas sensor heads. Suitable for use on a range of projects, including ambient monitoring and control, indoor air quality in public and commercial buildings, and health and safety monitoring at industrial sites.
Compatible with a range of gas sensor heads, including temperature and humidity
Flexible outputs enable use as a relay controller, gas transmitter, or monitoring network
Lightweight, discrete, and easily wall mountable
Product overview
The Series 900 enables flexible use due to a wide range of outputs and configurations. The monitor can operate in three ways:
As a relay controller with user configured set points to control an external device such as an ozone generator or initiate an alarm.
As a gas transmitter via the 4-20 mA output which allows connection to a PLC or current sensing device to provide gas concentration information for applications such as health and safety monitoring.
As a monitoring network via the RS485 digital output to enable gas monitoring at several indoor locations with information being logged to a central point.
The Series 900 is lightweight, discrete, and easily wall mountable. It requires a 12V power supply, which is user configurated to allow flexibility in installed locations.
There is also free to download configuration and networking software available under the downloads tab. The configuration software allows for quick and easy configuration of the alarm and control set points. The networking software can be used to log data from a network of monitors to a single PC.

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.
SM70 Fixed Monitor Ozone Sensors
The sensor board must be replaced when the SM70 Fixed Monitor Ozone sensor is due for calibration. Please contact our support team, and provide the serial number of your monitor.
What are the different output types?
Series 900 and Series 930 Fixed Monitor
Analogue output: 4-20mA (opto-isolated), 12-24V
