Temperature dependence
The output of an electrochemical sensor varies with temperature. The graphs below show the temperature-dependent variation of baseline and sensitivity, respectively. The results shown here are raw data (batch average) without any post-processing steps. The sensitivity and baseline are referenced to the signal at 20°C (reference point).
Please note: It is highly recommended to acquire the temperature dependence curves with
the whole instrument. The sampling system, the humidity, the electronics and the interaction
between the electronics and the sensor have a significant impact on the temperature
dependence of the final measurement reading.
