Solution miniature pour la surveillance en continu et temps réel du NH₃
Cairsens® NH₃
Les micro-capteurs Cairsens® permettent de mesurer des polluants spécifiques avec des résultats comparables aux méthodes de référence. Ils sont plébiscités dans le monde entier par nos clients à la recherche de haute technologie dans la surveillance de la qualité de l’air.
La précision de mesure est obtenue en limitant l’effet des interférences de l’humidité grâce à l’utilisation d’un filtre d’entrée spécifique et breveté combiné à un échantillonnage dynamique…
