Comparison of response characteristics of small CO2 ...

Portable infrared CO2 sensors, such as GMT222 (VAISALA) and LI-820 (LI-COR), are often used for soil CO2 efflux measurements; however, in general, these inexpensive small sensors are relatively inaccurate and slow to respond. The output signals are delayed as a result of diffusion processes in the sample cell and internal averaging calculations to ensure stable data output.
