Products defined by years of operator feedback
Cerex’s roots began in 1994 when our company founder began working in Atlanta, Georgia to develop the first commercially produced open-path FTIR remote sensing system.
In the years following, Cerex added UV-DOAS technology to further serve clients and expanded product lines to include gas analyzers for a variety of standard and custom applications

Decades of experience in research and development
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. This creates a more effective solution than other methods (such as electrochemical monitors).

Unmatched software and data-driven technology
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.
Cerex systems have the unique capability to perform multi-component analysis within a single instrument
We are committed to excellence in quality assurance and customer satisfaction
Since our beginnings over a decade ago, we continue to support each and every piece of equipment ever sold. Every Cerex system is guaranteed to perform, and we are here to ensure the continued success of your gas monitoring program. We maintain inventory to allow us to quickly service existing fielded products, such as the AirSentry (FTIR), UV Sentry, and UV Hound products. We welcome your inquiries about our existing products, and how they might meet your monitoring challenges.
