CO-BX Carbon Monoxide Sensors - Alphasense - #2

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.

Figure 4 shows hydrogen cross sensitivity for a typical batch of eight CO-BX sensors at 30^oC. All sensors show less than 5% cross sensitivity when 500ppm hydrogen is added to 950ppm carbon monoxide. The for a typical batch is less than 40 seconds.
