Response time (90%): 15 sec electrical response.

Within 60 seconds including replacement time of sampling gas (with 0.5L/min gas flow rate). Gas replacement time depends on the number of components,and measuring range.

A.5 Standard Requirements for Sample Gas

Flowrate: 0.5L / min ±0.2 L/ min

Temperature: 0 to 50°C

Pressure: 10 kPa (1.45 psi) or less (Gas outlet side should be open to the atmospheric air.)

Dust: 100 g/Nm3 in particle size of 1μm or less

Mist: Unallowable

Moisture: Below saturation at 2°C (condensation un- allowable).

Corrosive component: 1 ppm or less

Standard gas for calibration: Zero gas: Dry N2

Span gas: Each sample gas having concentration 90 to 100% of its measuring range (recommended). Concentration above 100% FS is unusable.

If an external zirconia O2 sensor is installed and calibration is carried out on the same calibration gas line:

Zero gas: Dry air or atmospheric air (provided without CO2 sensor).

Span gas: For other than O2 measurement, each sample gas having concentration 90 to 100% of its measuring range.

For O2 measurement: O2 gas of 1 to 2 vol %.
