Our products have been trusted all over the world by internationally recognized companies, government regulatory bodies, and communities – including the United Nations, the US EPA, the US Department of Energy.

Throughout 6 continents, we provide and support equipment for major companies in various manufacturing industries to ensure the safety of their surrounding communities and compliance with legal regulation.

Cerex’s roots began in 1994 when our company founder developed the first commercially produced open-path FTIR remote sensing system (the Cerex Air Sentry FTIR).

In the years following, we added UV-DOAS technology gas analyzers to expand product offerings and further serve clients for a variety of standard and custom applications.

Cerex’s engineering staff utilizes decades of experience to develop and manufacture analyzers for seamless integration into existing systems.

Combining technologies such as Broadband Infrared, Ultraviolet, or Tunable Diode Laser, with detection levels ranging from the parts-per-trillion to percent, gives our clients the flexibility to detect hundreds of compounds in a variety of applications.

The result: analyzers that are proven to be consistently reliable, accurate, and effective. Cerex’s analyzers create a more effective solution than other methods (such as electrochemical monitors).

In comparison to black box solutions, Cerex’s proprietary software collects readings every 5-30 seconds and archives raw spectrographic information for up to 1 year, allowing additional analysis of the presence of gases after the fact. This technology has been pivotal as defensible evidence in legal procedures.
