Cerex Monitoring Solutions

What Cerex Monitoring Solutions does

Cerex Monitoring Solutions, LLC is a privately held Atlanta, Georgia-based designer and manufacturer of multi-gas analyzers based on Fourier-Transform Infrared (FTIR) and Ultraviolet Differential Optical Absorption Spectroscopy (UV-DOAS) modalities. The company's instrument portfolio is organized into three families: open-path analyzers (UV Sentry, Air Sentry FTIR) for perimeter and fenceline coverage up to one kilometer; portable and fixed point analyzers (Hound Series, Micro FTIR, Shepherd FTIR, UV Scout) for local sampling, leak detection, HAZMAT response, and chemical warfare agent (CWA) detection; and fixed-installation analyzers (Cerex FTIR, FT5000, Aeres, UV3000, UV-FTIR) for cross-stack, extractive, or in-situ continuous emissions monitoring. A 2,048-wavelength high-resolution spectrometer combined with proprietary software enables detection limits down to parts per trillion across hundreds of gases including BTEX, VOCs, HAPs, TICs, and CWAs, with target-gas readings refreshed every 5-30 seconds and raw spectrographic data retained for post-analysis. Cerex's primary customers are major petroleum refineries, chemical manufacturers, government agencies (notably the US EPA and USDA), large livestock operations, and HAZMAT and industrial-hygiene end users; the analyzers are qualified against regulatory regimes including the HON Rule, USEPA Method 325 A/B, SCAQMD Rule 1180, BAAQMD Regulation 12 Rule 15, USEPA TO-16, and RCER-2020. Revenue is generated primarily through hardware sales of analyzers and associated multi-year service contracts, with pricing quoted on a custom basis through application-engineer-led consultations; go-to-market combines direct enterprise field sales with a strategic implementation partnership with Sonoma Technologies and a global network of international distributors.

Core offering

Cerex designs and manufactures FTIR (Fourier-Transform Infrared) and UV-DOAS (Ultra Violet Differential Optical Absorption Spectroscopy) multi-gas analyzers for real-time, simultaneous monitoring of multiple gases. The analyzers are used for fenceline monitoring, continuous emissions monitoring, process monitoring, ambient and indoor air quality monitoring, leak detection, and HAZMAT response, with detection limits down to parts per trillion. The product portfolio spans open path analyzers, portable point analyzers, and fixed installations.

Product overview

Cerex Monitoring Solutions designs and manufactures FTIR (Fourier-Transform Infrared) and UV-DOAS (Ultra Violet Differential Optical Absorption Spectroscopy) multi-gas analyzers for real-time air quality and emissions monitoring. The product portfolio consists of three main categories: Open Path Monitoring (UV Sentry, Air Sentry FTIR) for perimeter and fenceline detection over paths up to 1 kilometer; Portable Point Analyzers (Hound Series, Micro FTIR, Shepherd FTIR, UV Scout) for field sampling, leak detection, HAZMAT response, and Chemical Warfare Agent monitoring; and Fixed Installations (Cerex FTIR, FT5000 Series, Aeres, UV3000 Series, UV-FTIR) for continuous stack emissions monitoring, process control, and cross-stack sampling. The analyzers use proprietary software to display target gas readings every 5-30 seconds with detection limits down to parts per trillion, and are designed for regulatory compliance including HON Rule, USEPA methods, and various state regulations.

Broad incumbents

• Thermo Fisher Scientific: Thermo Fisher's Analytical Instruments segment supplies FTIR spectrometers, CEMS hardware, and air-quality monitoring solutions as part of a much broader lab-instruments portfolio — overlapping with Cerex on petrochemical and regulatory emissions applications.
• ABB: ABB's Measurement & Analytics business (formerly ABB Analytical) supplies FTIR and UV CEMS, process gas analyzers, and complete emissions monitoring systems to power, refining, and chemical customers globally — a direct competitor in fixed-installation CEMS where Cerex plays.
• Siemens: Siemens Process Analytics & CEMS (formerly part of Siemens Industry) offers extractive and in-situ gas analyzers for stack and emissions compliance — competing with Cerex's FT5000 and UV3000 fixed-installation lines.
• HORIBA: HORIBA's Process & Environmental segment sells FTIR, stack gas, and ambient emissions analyzers to automotive, refinery, and power markets — broadly overlapping with Cerex's spectrometer-based stack and process monitoring offerings.
• Teledyne Technologies: Teledyne's Environmental & Electronic Instrumentation segment (including Teledyne Analytical Instruments and Teledyne API) supplies CEMS-grade gas analyzers and emissions monitoring hardware — directly comparable on stack/continuous emissions and ambient monitoring.

Direct peers

• MKS Instruments: MKS Instruments (which acquired Spectra Sensors and the former Process Sensing Technologies portfolio) makes FTIR and other spectroscopic gas analyzers for CEMS, process analytics, and emissions monitoring — directly competing with Cerex's core product range and regulatory sweet spot.
• LI-COR Biosciences: LI-COR produces FTIR and optical gas analyzers for environmental, agricultural, and ecological emissions measurement — competing head-on with Cerex for livestock/agriculture emissions buyers (USDA, dairy industry) and indoor-air-quality accounts.
• Picarro: Picarro builds ultra-high-sensitivity trace-gas analyzers (CRDS-based) used for fenceline, methane, and ambient monitoring — overlapping with Cerex's parts-per-trillion detection claim and federal/state emissions use cases.
• SICK AG: SICK's gas-analysis and emissions-monitoring product lines (including MCS / SIDOR product families) target the same refinery fenceline, CEMS, and process-analyzer purchase cycle as Cerex, particularly in Europe and adjacent international markets.
• AMETEK: AMETEK's Process & Analytical Instruments division (including Western Research, Thermox, and AI ChE&E) supplies FTIR, CEMS, and process gas analyzers to refineries, petrochemical plants, and power generators — directly comparable to Cerex's fixed-installation and stack-monitoring lines.
