Datasheet | BrochureGuía de producto

Con éste analizador Cerex multi-gas con tecnología UVDOAS es posible monitorear distancias lineales (fenceline) que incluso excedan 1000 metros. Muy bajo costo de consumibles y mantenimiento asi como mínimas necesidades de infraestructura para su operación).

Algunas de las especies detectables son:  acetaldehidos, acroleína, amonia, benzeno, 1,3-butadieno, disulfito de carbon, cloro, dióxido de cloro, etilbenceno, formaldehidos, sulfuro de hidrógeno, naftaleno, óxido de nitrógeno, dióxido de nitrógeno, ozono, fenol, estireno, dióxido de azufre, tolueno, m-, o-, p-xilenos.

Algunos ejemplos de aplicaciones pueden incluir refinerías, incineradores, polos industriales, otras industrias petroquímicas, cementeras, minería, remediación medioambiental o monitoreo ambiental y de calidad de aire, etc.

Opcionalmente: C1 Div 2 A-D HAZLOC

EPA 40 CFR 63.658, BAAQMD Rule 12-15 y SCAQMD Rule 1180 compliance.
