Open-Path Gas Analyzer

Cerex Monitoring Solutions ("CEREX") systems are state-of-the-art instruments that can detect air pollutants such as Benzene (C₆H₆), Mercury (Hg), Sulfur Dioxide (SO₂), Ammonia (NH₃) and chemical warfare agents on a real-time basis. CEREX's portable point analyzers intake surrounding air via a sample port. Spectroscopy technology inside the analyzer then identifies ambient gases within the sample and determines the real-time concentration.

Cerex UV Sentry is an open-path gas analyzer designed to withstand extreme environmental conditions during the open path detection. It specializes in sensitive detection of key hazardous emissions such as Benzene (C₆H₆) and Chlorine (Cl₂) over 1000+ meters of fence-line paths. It sets the industry standard for time-resolved and gap-less fugitive emissions and chemical emergency monitoring.

Cerex Air Sentry FTIR is designed for rapid and real-time fenceline and zone monitoring of Air Toxics, Hazardous Air Pollutants, Combustion Gases, Alkanes, VOCs and Hydrocarbons all at low parts per billion (ppb) levels.

It was the first open path FTIR (Fourier-Transform Infrared Spectroscopy) to be commercialized and has continued to lead the industry with reliable performance and innovative features. It performs chemical detection and quantification of compounds using open-path FTIR DOAS (Differential Optical Absorption Spectroscopy).

It is the recognized and most reliable choice in open-path FTIR monitoring of industrial facilities, accidental releases and hazardous waste site emissions.
