Monitoring and Metering Product of the Year
Company Name: SignalFire Wireless Telemetry
Product Name: AirQ Scout-LCD
Supporting Statement:
SignalFire continues to demonstrate its commitment to customer-driven innovation with the release of the new AirQ Scout-LCD 900 MHz wireless gas detection system.
Following the successful launch of the AirQ Scout in June 2025, customers requested a solution with local indication and visual alarming. SignalFire’s response is the all-new AirQ Scout-LCD, delivering powerful wireless gas monitoring with an integrated LCD display for real-time visibility in the field.
Designed for seamless integration with SignalFire’s 900 MHz gateways, the AirQ Scout-LCD features an advanced smart sensor that stores critical diagnostics directly on the sensor, including remaining life, calibration history, and serial number—all accessible via the built-in LCD.
Pre-calibrated replacement sensors eliminate the need for field calibration, reducing maintenance time. By enabling real-time visibility into sensor health, the system supports more efficient, predictive maintenance and lowers overall operating costs.
The initial release of the AirQ Scout-LCD is designed to monitor hydrogen sulfide (H₂S) concentrations from 0 to 100 ppm. Future versions will support additional gases, including carbon monoxide (CO), carbon dioxide (CO₂), and lower explosive limit (LEL) measurements for various combustible gases.
With a wireless range of up to 0.5 miles (800 meters), the AirQ Scout-LCD enables gas detection in remote or hard-to-reach locations without the need for trenching or wiring. Its battery-powered design eliminates the need for external power supplies. For extended coverage, repeater nodes can be deployed to create a robust wireless mesh network.
When paired with the PATRIoT Gateway, multiple gas readings can be seamlessly integrated into existing control systems using Modbus RTU, Modbus TCP/IP, MQTT/Sparkplug, or EtherNet/IP. Users can also remotely monitor data through SignalFire Cloud, enabling real-time visibility, alarming, and reporting.
Engineered for hazardous environments, the AirQ Scout-LCD is pending Class I, Division 1 intrinsically safe certification. Its wireless design eliminates the need for IS barriers or additional components, simplifying installation and reducing system cost.
