Protecting People, Industry, and Environment
Cerex systems are state-of-the-art instruments that can detect air pollutants such as benzene, mercury, sulfur dioxide, ammonia, and chemical warfare agents on a real time basis.
Survey Site Emissions, Perimeter Leak Detection, Detection of Ambient Gas Levels
Cerex open path analyzers use spectroscopy technology to detect compounds in the open air over hundreds of meters. For decades, the UV Sentry (using UV-DOAS technology) and the Air Sentry FTIR (using FTIR technology) have helped government, industry, and communities monitor fugitive emissions with reliability, accuracy, and extreme sensitivity.
Point Analyzers
Local Area Sampling and Point Leak Detection
Cerex point analyzers intake surrounding air via a sample port. Spectroscopy technology inside the analyzer then identifies ambient gases within the sample and determines the concentration in real-time.
For decades, the small size and portability of the UV Hound, Shepherd FTIR, and Cerex FTIR have helped emergency personnel, hospitals, government agencies, and others quickly determine the toxicity of their environments.
The UV SCOUT is a new addition for 2025 – created for our customers needing the same reliable point technology and modest size of the Shepherd and Hound, but in a permanent, fixed solution for Leak Detection and Repair (LDAR) and Indoor Air Quality applications.

Fixed Installations & Emissions Systems
Analyzing Stacks or Process Streams
Cerex’s multi-gas analyzers use cross-stack, in-situ, or extractive monitoring methods to identify and measure the contents of emissions from industrial stacks.
They can also be configured into virtually any process monitoring application within refineries, chemical plants, and more.

Software and Technology
Within the broad landscape of gas detection methodologies, Cerex’s technology uses optical techniques to measure gas phase compounds
Continuous Monitoring Software (CMS)
Cerex analyzers use Continuous Monitoring Software (CMS) for analytical and data logging functions as well as to provide a user interface for the analyzer.
Running in the familiar Windows® operating system, CMS file storage architecture and controls are as intuitive as operating a personal computer.
