Analyseur d'ammoniac FTUV (NH₃) (transformée de Fourier)
BERYL 92M
Mesure ultra-rapide de NH3 (Temps de réponse ultra-rapide : < 2 secondes). L'utilisation de la gamme UV pour la mesure du NH3 a été spécifiquement choisie pour éviter toute interférence avec d'autres gaz d'émission majeurs (CO, CO2, H2O etc.) qui n’absorbent pas dans l’UV.
- Very high selectivity and maximum stability thanks to the UV Fourier Transform principle
- Ultra-fast response time (< 2 sec)
- High speed DSP processor
- No risk of interferences or quenching effect due to CO, CO2 or H2O
- No internal converter, ultra-low maintenance
- High lifetime of the lamp (> 1 year of continuous use)
- Heated chamber (190°C)
- Touch screen
- Multilingual software
- Automatic compensation of pressure and temperature variations
- Engine exhaust gas monitoring
- Emission monitoring (CEMS)
- Process control (DeNOX SCR and SNCR)
