Perf erformance Data CL2-A1 Performance Data Figure 2 Sensitivity Temperature Dependence Figure 2 shows the variation in sensitivity caused by changes in temperature. This data is taken from a typical batch of sensors. The mean and 95% confidence intervals are shown. Chlorine gas tests are difficult, especially at higher temperatures. Zero output, referenced to 20oC (equivalent ppm) Figure 3 Zero Temperature Dependence 1 Figure 3 shows the variation in zero output caused by changes in temperature, expressed as ppm gas equivalent, referenced to zero at 20oC. This data is taken from a typical batch...
