Complete Nitrogen Compound Measurement in Real Time
The MEXA-ONE-XL-NX simultaneously measures NO, NO2, N2O and NH3, giving engineers synchronized data from a single analyzer for understanding engine and aftertreatment performance.
Example of synchronized, real-time nitrogen compound measurement during changing operating conditions.
- Wide measurement ranges support engine-out, pre-catalyst, post-catalyst and tailpipe applications
- Fast response captures changes during transient operating conditions
- One analyzer supports the evaluation of NOx conversion, ammonia slip and N2O formation
- Synchronized measurement data can be correlated with engine conditions and control events
High-Precision Measurement with IRLAM™ Technology
HORIBA’s IRLAM™ (Infrared Laser Absorption Modulation) technology provides sensitive and stable measurement in complex exhaust gas mixtures.
- High sensitivity and low-noise performance at low concentrations
- Minimal interference from other exhaust gas components
- Direct wet measurement without removing water from the sample
- No NO2 converter required for NOx measurement
- Consistent response without converter deterioration or ammonia poisoning
- Reduced maintenance associated with converters, ammonia-protection filters and other consumable components
