| Principle |
NO, SO2, CO, CO2, N2O, CH4: Non-dispersive infrared sensor
O2: built-in paramagnetic sensor or external zirconia sensor (ZFK7, optional)
|
| Components |
1 component: NO, SO2, CO, CO2, CH4, N2O
2 components: NO + SO2, NO + CO, CO2 + CO, N2O + CO2
3 components: NO + SO2 + CO, N2O + CO2 + CO
4 components: NO + SO2 + CO + CO2, NO + SO2 + N2O + CO2
CH4 can be combined.
O2 measurement can be added to above all.
