Measured components(standard) | CO, HC, CO2, AFR, LAMBA, (O2, NO option) |
Measurement principle | CO, HC, CO2: Non-dispersive infrared (NDIR) Air-to-fuel ratio (AFR), Excess air ration (lambda): carbon balance method or Brettschneider method (with O2 measurement). AFR and lambda are calculated by the carbon balance method in standard configuration. |
Conformed standard | OIML Class 0 - CE - FCC |
Ambient humidity | Under 90% relative humidity |
