CL2-B1 Chlorine Sensors

Product catalog summary

Performance Specifications:

Sensitivity: -700 to -1100 nA/ppm in 10ppm Cl2.
Response Time: Less than 60 seconds to reach 90% of the response from zero to 10ppm Cl2 with a 33W load resistor.
Zero Current: ±0.2 ppm equivalent in zero air.
Resolution: RMS noise less than 0.02 ppm equivalent with a 33W load resistor.
Range: Performance warranty up to 20 ppm.
Linearity: Error at full scale less than 0.2 ppm, linear at zero and 10ppm Cl2.
Overgas Range: Stable response to gas pulse up to 100 ppm.

Lifetime Specifications:

Zero Drift: Less than 0.1 ppm equivalent change per year in lab air.
Sensitivity Drift: Less than 5% change per year in lab air, tested monthly.
Operating Life: More than 24 months until 80% of the original signal is maintained (24-month warranty).

Environmental Specifications:

Temperature Sensitivity: 85% to 97% output at -20°C and 50°C compared to 20°C at 10ppm.
Zero Temperature Change: ±0.15 ppm equivalent change at -20°C and -0.1 to -0.25 ppm at 50°C from 20°C.
Cross Sensitivity:
- NO: Less than 0.5% at 50ppm.
- SO2: Less than -2% at 20ppm.
- NO2: 100% at 10ppm.
- H2: Less than 0.1% at 400ppm.
- H2S: -100% at 20ppm.
- CO: Less than 0.1% at 400ppm.
- C2H4: Less than 0.1% at 400ppm.
- NH3: Less than 0.1% at 20ppm.
- CO2: 0% at 5% (Vol).

Key Specifications:

Temperature Range: -20°C to 50°C.
Pressure Range: 80 to 120 kPa.
Humidity Range: 15% to 90% relative humidity continuously.
Storage Period: 6 months at 3 to 20°C in a sealed pot.
Load Resistor: 33W for optimum performance.
Weight: Less than 13 grams.

Additional Notes:

Sensors are tested at ambient conditions with a 10 ohm load resistor unless otherwise stated.
Exposure above 85% rh and 40°C is warranted for a maximum of 10 days, with recovery possible at lower humidity and temperature.
