Products

• Works out of the box: Highly integrated hardware and software (Edgar) allows you to install your instrument virtually anywhere. Turn the instrument on and it will start sounding the atmosphere and send you relevant data!
• Trust your results: End-to-end performance validated in the field by the scientific community
• Manipulate less data: Produces atmospheric parameter profiles directly, not only interferograms or spectra
• See further: Highest sensing performances available, using state-of-the-art technology and software algorithms
• Use less manpower: True unattended 24/7 operation, with tools to help you keep track of its operation.
• Work from anywhere: 100% remotely controllable

• Measures temperature, water vapor, O₃ CO, CO₂, CH₄ and NO_x vs altitude (Atmospheric profiles)
• Generate temperature and moisture profile every 2 minutes (near real time)
• High accuracy measurements for weather applications
• High vertical resolution and high temporal resolution
• Integrated and automatic radiometric calibration
• Extensive instrument health monitoring
• Network-centered architecture
• Extensive remote monitoring for maintenance
• Accepts additional user devices via the built-in USB, LVDS, and CameraLink interfaces
• Rugged construction (field deployable)
