The LI-7500A is a high speed, high precision, non-dispersive infrared gas analyzer that accurately measures densities of carbon dioxide and water vapor in-situ. With the eddy covariance technique, these data are used in conjunction with sonic anemometer wind speed to determine the fluxes of CO2 and H2O into and out of ecosystems.
The LI-7500A accepts analog data from a sonic anemometer and logs complete data sets to a removable USB storage device.
Low power consumption: 12 W during normal operation
High Speed: up to 20Hz bandwidth
High Precision: 0.11 ppm CO2, 0.0047ppt H2O*
Excellent stability
Absence of tubing eliminates delays and sorption effects
No Signal Attenuation for CO2/H2O
Suitable for harsh environments
Analog inputs and on-board data storage allow the LI-7500A to log complete eddy covariance data sets (CO2, H2O, U, V, W, and TS , and other variables)
* at 10 Hz, at 370 ppm CO2 and 10 mmol/mol H2O
