World-renowned multi-gas analyzers and custom spectroscopy solutions
Who We Are
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
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”.
Unlike competing products, Cerex’s equipment uses little to no moving parts that wear out. Combined with inherent calibration (preventing time-consuming troubleshooting), and integrated networking, our products provide peace of mind and low cost of ownership. Our devices, such as the UV Sentry HC, are highly sensitive, precise, and reliable in rough field conditions.
Built for regulation compliance
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.
How does Cerex equipment operate?
Cerex equipment can reliably detect hundreds of gases
Our acclaimed equipment couples UV DOAS or FTIR technology with ultra low minimum detection limits (down to parts per trillion)
UV-DOAS or FTIR Technology
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.
