Greenhouse Gas System 2
GHG-2 System includes the LI-7700 Open Path CH4 Analyzer, LI-7200 CO2/H2O Analyzer (includes the LI-7550 Analyzer Interface Unit), and the 7200-101 Flow Module. This system provides an integrated solution for greenhouse gas flux measurements in environments with frequent rain, snow, or fog.
GHG-2 Features:
- Measures CH4, CO2, and H2O with 35 W of power
- Flow Module integrates flow rate and diagnostic data with the data set
- Short intake tube (typically 0.5 to 1.0 m) minimizes time delays from tubing for CO2/H2O
- Minimal tubing attenuation of H2O
- 90-95% temperature attenuation for CO2/H2O measurements
- Sensors are easily co-located with the sonic anemometer sample volume
LI-7700 Open Path CH4 Analyzer
- High speed, high precision methane density measurements.
- Self-cleaning mirror minimizes maintenance requirements.
- Temperature controlled mirrors and a radiation shield reduce condensation in the optical path.
LI-7200 Enclosed CO2/H2O Analyzer
- Based on the proven LI-7500.
- Designed to provide continuous CO2/H2O measurements through rain, fog, and snow.
- Includes the LI-7550 Analyzer Interface Unit, which houses digital signal processing electronics for the LI-7200.
- High precision, fast response.
- Provides versatile output options.
- 4 analog inputs for data from a sonic anemometer.
