Gas measurement :
-
NO - SO2 - CO - CO2 - O2 (see possible configurations on page 2)
Gas analysis principle :
-
NO - SO2 - CO - CO2 Non-dispersive Infrared Absorption (NDIR micro-flow) No interference of gaseous water on NO and SO2 detector
-
O2 Galvanic fuel cell (standard) Paramagnetic detector (optional with analyser model GAS 3070 R PMGO2)
Gas Ranges1:
-
NO From 0-200 ppm to 0-5000 ppm (NOx with optional external NO2 converter)
-
SO2 From 0-200 ppm to 0-5000 ppm
-
CO From 0-500 ppm to 0-5000 ppm2
-
CO2 From 0-5% to 0-25%
-
O2 From 0-5% to 0-25%
1 intermediary measuring ranges are available
2 CO range up to 9999 ppm or in % volume on request
Resolution : 1 ppm (CO, NO, SO2) or 0.01% (CO2, O2)
Repeatability : ± 1% of Full Scale
Linearity < ± 2% of Full Scale for NDIR micro-flow detectors / < ± 0,3% for oxygen sensor
