Zero Current: Less than ±20 ppm equivalent in zero air.
Resolution: RMS noise less than 5 ppm equivalent.
Range: Performance warranty up to 10,000 ppm CO.
Linearity: Error less than 500 ppm at full scale.
Overgas Limit: Stable response up to 100,000 ppm.

Lifetime and Drift:

Zero Drift: Less than 1 ppm equivalent change per year.
Sensitivity Drift: Less than 4% change per year.
Operating Life: More than 24 months until 80% of the original signal.

Environmental Conditions:

Temperature Sensitivity: 70 to 90% at -20°C and 102 to 112% at 50°C, referenced to 20°C.
Zero Temperature Change: Less than ±3 ppm at -20°C and less than ±5 ppm at 50°C.

Cross Sensitivity:

Filter Capacities: H2S: 4,000,000 ppm-hours, NO2: 10,000,000 ppm-hours, NO: 2,000,000 ppm-hours, SO2: 5,000,000 ppm-hours.
Gas Sensitivities: Less than 0.1% for H2S, NO2, NO, SO2, Cl2, and less than 45% for H2, less than 2% for C2H4, less than 0.1% for NH3.

Key Specifications:

Temperature Range: -30 to 50°C.
Pressure Range: 80 to 120 kPa.
Humidity Range: 15 to 90% rh continuous.
Storage Period: 6 months at 3 to 20°C.
Load Resistor: Recommended 10 to 47 Ω.

Performance Data:

Temperature Dependence: Figures illustrate sensitivity and zero output variations with temperature changes.
Response to CO: Non-linear response to step changes in CO concentrations is shown.

Notes: All sensors are tested under ambient conditions with a 10-ohm load resistor. Users should verify suitability under their own conditions. Disposal instructions are provided by the manufacturer.
