The wave length is selected to avoidcross-sensitivity with other gases.0-10% CO2CO2 SensorRangeResolution 0.01% CO2Repeatability @ 0% CO2 = ±0.05% CO2@ 10% CO2 = ±0.15% CO2Response time With a flow rate of 100mls/min = 50 secondsTemperature drift 0.1% of full scale /CTypical Warm up time 10 minutesOperating temperaturerange 0-45ºCCO2 cell expectedoperating life 5-10 yearsCross sensitivity None1.Range 0-50% O20.1% O2Repeatability @ 21% O2 0.2% O2Response time With a flow rate of 100mls/min = 20 secondsTypical Warm up time 10 minutesOperating temperaturerange 0-45ºCO2 cell expectedoperating life 2 years in 21% O2Cross sensitivity:-The O2 cell has been tested for cross-sensitivity to a number of gases. The gasconcentrations used and the response of the O2 cell are summarised below:-GasO2 Cell Output(%O2equivalent)GasO2 Cell Output(%O2equivalent)16%CO2/Balance N2 <0.01 6%CO/Balance N2 <0.0025%H2 /Balance N2 <0.001 3000ppm NO/Balance N2 <0.0022000ppmn-hexane/Balance N2<0.01These figures show that, of the gases tested, none show a sufficiently large cross-sensitivity to cause any inaccuracy in readings. In addition the baseline wasunaffected by exposure to these gases.O2 0-5V = 0-50% max output 10VCO2 0-5V = 0-5% max output 10V (10%)4-20 mAO2 SensorAnalogue OutputOptionResolution2.For zero N2 100%For Calibration Typically 20% O2, 8% CO2, remainder N2The exact calibration values are normally supplied with the gasPush connector for 6mm OD tubingVoltage 115 or 230 VAC +/- 10% (switchable)Instrument Size 190mm wide x 190mm high x 330mm deepPacked Size 300mm wide x 310mm high x 410mm deepInstrument Weight 6 kgsPacked Weight 7 kgsQty.
