Cerex Monitoring Solutions, LLC.
Cerex designs and manufactures FTIR and UV-DOAS multi-gas analyzers to solve complex monitoring challenges. For over 20 years, Cerex has used solid spectroscopy techniques to simultaneously monitor multiple gases in real time. Our analyzers are used for Fenceline Monitoring, Continuous Emission Monitoring, Process Monitoring, Ambient Air Quality Monitoring, Indoor Air Quality Monitoring, Leak Detection, Hazmat First Response, and more.
World renown multi-gas analyzers and custom monitoring solutions
Real-time measurements, instant data
Cerex’s unique, proprietary software uses algorithms to display target gas readings every 5-30 seconds – resulting in accuracy that is unmatched in the market.
Cerex analyzers save raw spectrographic information, allowing further analysis after the fact. Our clients can see what compounds are in the air at any given time – an advantage compared to “black box solutions”.
Designed from the ground up, our analyzers are specifically engineered to meet regulations, including the US EPA criteria for fence-line and refinery benzene monitoring. Click here to see how Cerex open-path analyzers can solve your application challenges.
To provide simple, effective, off the shelf and customized gas analysis systems for industry, government and the community
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 ensure compliance with legal regulation.
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 (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 is 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.
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.

Internal Radiation Source
A deuterium or xenon lamp creates an Ultraviolet (UV) or Infrared (IR) light beam (depending on the application)
Specially designed optics focus the UV or IR beam and project it through the gas sample
Receiver & Spectrometer
Cerex receiver optics collect the light and focus it into a high resolution spectrometer (2,048 discreet wavelengths)
Cerex’s continuous monitoring software analyzes the received light, and reports a concentration for each target gas present in the sample in real-time
Chemical Ware Agents
Toxic Industrial Chemicals
Hazardous Air Pollutants
Volatile Organic Compounds
Benzene, Toluene, Ethylbenzene, Xylenes
Chlorine, Butadiene, Carbon Disulfied, Sulfur Dioxide, Naphthalene, and more
Cerex offers both UV-DOAS and FTIR technology based analyzers so you can target your gases of interest at the lowest detection limits possible. Depending on your application, there will be pros and cons to each option.
Generally, UV-DOAS based analyzers are the most cost-effective choice for focusing on a few different gases with extreme sensitivity. In contrast, FTIR based analyzers come at a higher price tag but are highly adept at monitoring dozens of gases simultaneously – with laboratory sensitive quality.
