SPECIFICATION SHEET FOR CO SENSOR TYPE CO/MF-500
TEMPERATURE DEPENDENCE
The output of an electrochemical sensor varies with temperature. The graphs below show the variation in output with
temperature for this type of sensor. The results are shown in the graphs as a mean for a batch of sensors, along with
confidence intervals corresponding to ±3 times the standard deviation. The sensitivity dependence is expressed as a
percentage of the signal at 20 °C.
