The temperature recorded in the output, is it ambient or leaf temperature?

The temperature sensor is measuring the ambient temperature inside the measurement crown of the Dualex device, therefore, it can slightly vary from the surrounding temperature and does not reflect the actual leaf temperature. The measured temperature value is an important technical factor in reading calibrated results of Chlorophyll, Flavanol and Anthocyanins as the calculation process takes into account the temperature dependence of the LEDs.
