CL2-B1 Chlorine Sensor PERFORMANCE Sensitivity nA/ppm in 10ppm Cl2 -600 to -1150 Response time t90 (s) from zero to 10ppm Cl2 (33Q load resistor) < 60 Zero current ppm equivalent in zero air ± 0.4 Resolution RMS noise (ppm equivalent) (33Q load resistor) < 0.02 Range ppm limit of performance warranty 20 Linearity ppm error at full scale, linear at zero and 10ppm Cl2 < ± 0.2 Overgas limit maximum ppm for stable response to gas pulse 60 LIFETIME Zero drift ppm equivalent change/year in lab air < 0.03 Sensitivitydrift % change/year in lab air, monthly test < 6 Operating life months until 80% original signal (24 month warranted) > 24 ppm equivalent change from 20°C < 0 to -1 % measured gas % measured gas % measured gas % measured gas % measured gas % measured gas % measured gas % measured gas % measured gas SPECIFICATIONS Pressure range kPa 80 to 120 Humidity range % rh continuous (see note below) 15 to 90 Storage period months @ 3 to 20°C (stored in sealed pot) 6 Load resistor Q (for optimum performance) 33 Note: Above 85% rh and 40oC a maximum continuous exposure period of 10 days is warranted. Where such exposure occurs the sensor will recover normal electrolyte volumes when allowed to rest at lower % rh and temperature levels for several days. At the end of the product’s life, do not dispose of any electronic sensor, component or instrument in the domestic waste, but contact the instrument manufacturer, Alphasense or its distributor for disposal instructions. NOTE: all sensors are tested at ambient environmental conditions, with 10 ohm load resistor, unless otherwise stated. As applications of use are outside our control, the information provided is given without legal responsibility. Customers should test under their own conditions, to ensure that the sensors are suitable for their own requirements.

Perf erformance Data CL2-B1 Performance Data Figure 2 Sensitivity Temperature Dependence 110 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 can be difficult and non-repeatable, especially at high 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.
