Airdar is capable of measuring any compound for which there is a detector.
How It Works
1. Visualizes a plume in data
2. Finds the direction of the source
3. Triangulates from multiple sampling points
4. Quantifies emissions once distance to source is known

Airdar Analysis
An Airdar Analysis uses emissions monitoring data to provide actionable information on emission sources both on- and off-site. After a baseline has been established, the most important emission sources can be located and quantified. On-site emission sources have been located within as few as 3 to 4 m, while off-site emissions have been identified from as far as 22 km away.
One or more compounds can be monitored at the same time. We offer one-time projects or long-term emissions monitoring with real-time notifications about emission rates, Real-Time Airdar.
An Airdar Analysis can be done using data generated by an Airdar equipment package, or using data provided by the client (including historical data).
Source locations and emission rates are shared on our emissions monitoring dashboard. Our dashboard is a tool that provides powerful information to operators, designed to streamline workflow. With real-time tracking, operators can get needed information to make critical decisions.
Monitoring Equipment
Emission monitoring equipment can be provided to clients to monitor and measure their emissions. Each equipment package consists of off-the-shelf detectors and a wind monitor. A traditional Airdar equipment package includes a central instrumentation cabinet connected to remote sampling locations via tubing and can monitor several compounds. For methane monitoring, a small stand-alone sensor with a low detection limit can be offered as a low-cost solution for continuous methane emissions monitoring.
Airdar equipment packages can be rented or purchased by the client. Alternatively, if minimum requirements are met, the Airdar system can be implemented using existing equipment on a site.
The Airdar system is designed to minimize onsite maintenance activities. Bi-annual or annual maintenance may be required to replace calibration gas containers, vacuum pumps, flow sensors, and troubleshoot. Airdar remotely monitors the equipment and can remotely engage backup components such as pumps and sensors. This allows the system to continue running until the next scheduled maintenance time. If a component malfunctions, the system will automatically send a notification and Airdar will assess its criticality. Airdar will work with clients to schedule and perform necessary maintenance activities as needed during the deployment of the monitoring system.
