Familia de analizadores portátiles marca Cerex MS, con tecnología UV DOAS (Hound, Mini Hound y Micro Hound). Pueden configurarse con celdas de medición cuyo rango de paso óptico es desde 2.5mts a 21.6mts, logrando así niveles de detección de unas pocas ppb.
Además su moderno procesador le permite obtener y procesar en tiempo real resultados de muestras con las más variadas composiciones.
Permite incorporarle celdas electroquímicas de medición de gases que no sean detectables en UV, entradas y salidas analógicas, una estación meteorológica portable, comunicación wi-fi y/o via modem celular, salidas digitales.
Una batería interna que independiza por más de 4 horas de la fuente de energía fija.
Algunos de las especies detectables son: 1,3 Butadiene C4H6), Acetaldehyde (C2H4O), Acetone (CH3COCH3), Acrolein (C3H4O), Ammonia (NH3), Benzene (C6H6), Carbon Disulfide (CS2), Chlorine (Cl2), Chlorine Dioxide (ClO2), Ethyl Benzene (C8H10), Formaldehyde (CH2O), Hydrogen Sulfide (H2S), Isoprene (C5H8), Mercury (Hg), Naphthalene (C10H8), Nitric Oxide (NO), Nitrogen Dioxide (N2O), Nitrous Acid (HNO2), Oxygen (O2), Ozone (O3), Phenol (C6H5OH), Styrene (C8H8), Sulfur Dioxide (SO2), Toluene (C6H5CH3), Trimethylbenzene (C9H12), O-Xylene, M-Xylene, P-Xylene (C8H10).
