Figure 2 shows the variation in sensitivity caused by changes in temperature. Repeatable temperature dependence at elevated temperatures allows more accurate temperature compensation.

This data is taken from a typical batch of sensors. The mean and ± 95% confidence intervals are shown.

Figure 4 shows sensor output for increasing concentrations of CO, up to twice the specified overgas range. Data are derived from eight sensors taken from a typical production batch.

This stepped overgas test shows the robustness of the sensor with fast response and straight plateaus at each step.
