LI-6800 Leaf Temperature Thermocouple Height

LI-6800 Leaf Temperature Thermocouple Height

Leaf temperature is an important input to many parameters calculated on the LI-6800, including stomatal conductance (gsw) and leaf intercellular CO2 concentration (Ci). The LI-6800 leaf temperature probe is a Type E thermocouple mounted on flexible material (Figure 1). The thermocouple junction is a ~0.008” diameter bead. The bead is too small to be seen without magnification (Figure 2).

Accurate measurement of leaf temperature requires that the thermocouple bead be high enough to ensure it is making contact with the…
