The Aeroqual Series 900 Fixed Monitor (S900) is a versatile and reliable solution for continuous gas monitoring and control. Designed for precision and adaptability, this monitor supports a range of toxic gas sensors and can also incorporate optional temperature and humidity sensors for comprehensive environmental monitoring. Built to measure and manage ozone concentrations, the S900 seamlessly integrates with a variety of hardware systems—making it ideal for industrial, commercial, and laboratory applications.
Three Powerful Modes of Operation
The Series 900 Fixed Monitor can be configured to operate in one of three flexible modes, allowing it to fit effortlessly into diverse applications:
- Relay Controller:
Operate as a standalone relay controller with user-configured set points. The monitor can control an external device—such as an ozone generator—or trigger an alarm when ozone levels reach preset thresholds. - Ozone Transmitter (4–20 mA Output):
Use the 4–20 mA output to connect the S900 to a PLC or current-sensing device. This enables precise, real-time transmission of ozone concentration data for health, safety, and process control applications. - Ozone Network (RS485 Digital Output):
Build an integrated ozone monitoring network with multiple S900 monitors connected via RS485 digital output. Data can be logged to a central computer for efficient system-wide management and reporting.
Easy Installation and Maintenance
Compact, lightweight, and easily wall-mountable, the S900 offers maximum flexibility in installation locations. It operates using a 12V power supply, which can be user-configured or purchased as an accessory.
The monitor’s interchangeable sensor heads make maintenance simple—just remove the old sensor and plug in the new one. Each sensor head can be returned to Aeroqual for recalibration, ensuring long-term accuracy and reliability. For optimal performance, it’s recommended to calibrate the S900 annually and replace the sensor after approximately two years of service life.
Software for Configuration and Networking
Aeroqual provides free configuration and networking software, available for download under the “Downloads” section.
- Configuration Software: Quickly and easily set alarm thresholds and control parameters directly from your PC.
- Networking Software: Log and analyze data from multiple S900 monitors on a single network, enabling centralized tracking and management of ozone levels across multiple indoor locations.
