Leaf temperature error from heat conduction along thermocouple wires

Heat conduction through the wires is one source of thermocouple (TC) error. Leaf temperature measurement may be affected by this error if the leaf-to-air temperature difference is large and contact between TC and leaf is inadequate. Selection of small diameter TCs with low thermal conductivity, as well as good contact with the leaf, are possible solutions to the problem. A laboratory experiment was carried out to determine conduction error as a …
