Introduction to Sensor
Integrated CO2 and H2O Open-Path Gas Analyzer and 3-D Sonic Anemometer (HMP155A)
Patented Design
The IRGASON® combines an open-path gas analyzer and a three-dimensional sonic anemometer into a single, compact instrument optimized for eddy-covariance flux measurements. This patented integration simplifies installation, reduces alignment challenges, and improves overall measurement accuracy compared to separate sensors.
