Gas Detection when and where you need it.
Modular platform with replaceable gas sensor.
Continuous or scheduleded gas measurement.
Low maintenance, direct cloud connectivity.

Modular wireless gas detection platform.
The RANGER AirQ is an emissions monitoring platform with integrated cellular communications. It monitors the presence of a gas and transmits the measurement wirelessly over LTE-M/NB-IoT cellular networks. The data is transmitted to the SignalFire Cloud and can be sent using MQTT/SparkPlug to a private cloud platform supporting this messaging standard. The gas detection sensor is powered from the built-in 72Ah battery. The measurements are also pin pointed geographically by the GPS module inside the RANGER AirQ.
Unmatched performance and longevity.
The RANGER AirQ is engineered to meet the stringent demands of modern environmental monitoring.
The first version of the AirQ will be equipped with a methane sensor capable of detecting and measuring methane concentrations from as low as 50 ppm to as high as 1,000,000 ppm. This new product is field-tested to accurately detect methane emissions at a rate of 2 SCFH at distances up to 30 feet. The AirQ’s methane sensor automatically compensates for environmental conditions providing excellent accuracy and stability for years without the need for recalibration. Other gas sensors are to be announced in the future.

Revolutionizing Greenhouse Gas Monitoring.
The RANGER AirQ is a modular wireless gas detection platform with integrated cellular communications. It monitors the presence of a gas and transmits the measurement wirelessly over LTE-M/NB-IoT cellular networks. The data is transmitted to the SignalFire Cloud and can be sent using MQTT/SparkPlug to a private cloud platform supporttng this messaging standard. The gas detection sensor is powered from the built-in 72Ah battery. The measurements are also pin pointed geographically by the GPS module inside the RANGER AirQ.
The smart gas sensor uses the latest in smart gas sensor technology providing for low power demand, stable and accurate measurement as well as long term stability with little to no calibration required. It automatically compensates for temperature and humidity when sampling a measurement and therefore delivers accurate measurements with low drift. It’s low power requirements allow for long battery life.
