Multi-Gas FTIR and UV DOAS Analyzers

Cerex’s roots began in 1994 when the company founder, Tom Wisniewski, began working in Atlanta, Georgia to develop and manufacture one of the first Open Path FTIR remote sensing systems. Since that time, many of the concepts of absorption spectroscopy have been applied and developed into instrumentation solutions. Core technologies that we employ include broadband Infrared and Ultraviolet, as well as tunable diode laser.

Systems built in 1994 are operational and still in use today. This, in itself, demonstrates our continued commitment to excellence in quality assurance and customer support. Since our beginnings over a decade ago, we continue to support each and every piece of equipment ever sold. 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. Also, talk to our application engineers about any unique needs you may have. Cerex specializes in quickly bringing custom-engineered solutions to final product, while maintaining the highest quality standards. Every Cerex system sold is guaranteed to perform, and we are here to insure the continued success of your gas monitoring program.

Cerex specializes in custom solutions for custom applications.

Our engineering staff focuses on developing and manufacturing analyzers to integrate seamlessly into existing systems. With detection levels ranging from the parts-per-trillion to percent, our products can meet your gas detection needs. Our products utilize technologies ranging from broadband infrared or ultraviolet, to tunable diode laser. This flexibility gives our clients the capability to detect hundreds of compounds. For any application we can customize a solution for you with our extensive list of options. Our DOAS (Differential Optical Absorption Spectroscopy) gas detection provides a more effective solution over electrochemical monitors.

  • Open-Path Analyzers
    Our open-path analyzers detect gases across paths up to one kilometer. Use Cerex remediation gas detectors to survey site emissions, perimeter leak detection, and detection of ambient gas levels.
  • Stack Analyzers
    Monitor stack emissions via cross-stack, extractive, or in-situ sampling with our versatile analyzers. Cerex stack gas detectors analyze hundreds of compounds over a large spectral range.
  • Point Analyzers
    Determine safe conditions with our ultra portable ppb point detectors. Cerex point gas detectors are ideal for local area sampling and point leak detection.
  • Process Analyzers
    Monitor critical chemical concentrations within your sealed process stream. Cerex process gas detectors can interface with alarms, send email alerts, and record data for advanced analysis.
