Mesure de NH₃ par laser (TDLS)
La série LGD 2M utilise la technologie TDL pour la mesure de NH3 et est conçue pour être intégrée dans nos baies d’analyse de gaz moteur, pour mesures rapides et fiables d’ammoniac pré ou post catalyse.
ENVEA propose ce système de mesure de NH3 rackable et de faible encombrement (rack 3U) intégré dans ses baies de mesure clé-en mains pour des mesures en continu sur gaz moteurs.
Son principe de mesure de base sur la détection de gaz par spectrométrie laser à diode accordable (TDLS) qui présente des avantages et une valeur exceptionnelle pour le client.
