MOD-1040 Oxygen Analyzer
MOD-1040 High-Pressure Oxygen Analyzer
Direct In-Situ Oxygen Measurement from 1 ppm to 100% O₂
Real-Time Oxygen Monitoring for Hydrogen, Electrolyzers and Critical Process Applications
The MOD-1040 High-Pressure Oxygen Analyzer is a next-generation industrial oxygen analyzer designed for continuous, real-time oxygen measurement in hydrogen, oxygen, and process gas applications operating under the most demanding conditions. The analyzer performs true in-situ oxygen measurement without sample extraction, conditioning systems, pumps, filters, or transport lines, providing immediate process visibility and superior measurement reliability.
The MOD-1040 measures oxygen concentrations from 1 ppm to 100% O₂ on a single platform, operates at process pressures up to 350 barg (5,076 psi), delivers T90 response times below 5 seconds, and is certified for ATEX and IECEx Zone 1 hazardous area installations and SIL 2 safety applications. UL, cUL, and Class I Division 2 approvals are currently pending, making the analyzer suitable for global deployment across hydrogen, industrial gas, petrochemical, natural gas, biogas, and energy infrastructure projects.
Designed specifically for hydrogen production, PEM and alkaline electrolyzers, hydrogen storage and transportation systems, industrial gas facilities, refineries, petrochemical plants, ammonia production, and natural gas infrastructure, the MOD-1040 combines advanced optical sensing technology with automatic pressure and temperature compensation, Bluetooth-enabled commissioning, flexible calibration options, and multiple corrosion-resistant material selections for the most aggressive process environments.
Field-proven across petrochemical, refinery, natural gas, and biogas installations worldwide, the MOD-1040 delivers reliable trace oxygen measurement down to ppm levels in process streams containing hydrocarbons and high concentrations of H₂S. This unique capability enables accurate oxygen monitoring in applications where conventional analyzers often suffer from reduced performance, excessive maintenance, or premature sensor degradation. The result is superior process safety, improved asset protection, enhanced product quality, corrosion prevention, catalyst protection, gas quality assurance, and lower operating costs in some of the industry’s most demanding environments.
Unlike conventional extractive oxygen analyzers that introduce transport delays, increase maintenance requirements, and require costly sample conditioning systems, the MOD-1040 measures oxygen directly at the process location, enabling faster detection of gas crossover events, improved process safety, enhanced hydrogen purity control, reduced CAPEX and OPEX, and superior performance for Advanced Process Control (APC), Digital Twins, AI-based optimization, and predictive maintenance applications.

Industry-Leading High-Pressure Oxygen Analyzer
MOD-1040 is specifically designed for applications where conventional oxygen analyzers struggle to operate reliably.
With capability for direct installation in process lines operating at pressures up to 350 barg, the analyzer provides accurate oxygen measurement under conditions commonly associated with:

Unlike traditional extractive oxygen analyzers that require pressure reduction stations, sample transport tubing, regulators, pumps, and conditioning systems, the MOD-1040 performs oxygen measurement directly at the process location.
Why Conventional Oxygen Analyzers Are Not Suitable for Modern Hydrogen Applications
Most traditional oxygen analyzers were developed for low-pressure industrial processes and rely on extractive sampling systems that require pressure reduction stations, sample conditioning equipment, transport tubing, pumps, filters, and vent systems.
In modern hydrogen production facilities, electrolyzers, hydrogen storage systems, and high-pressure gas networks, these sampling systems introduce additional complexity, measurement delays, maintenance requirements, and potential leak points.
The MOD-1040 eliminates these limitations through direct in-situ measurement, allowing oxygen concentrations to be measured directly within the process stream at pressures up to 350 barg. The result is faster detection of oxygen contamination, improved process safety, reduced maintenance requirements, lower lifecycle costs, and significantly improved analyzer reliability.

Hydrogen Crossover Detection and Electrolyzer Protection
One of the most critical safety challenges in PEM and Alkaline electrolyzers is the migration of hydrogen into oxygen streams or oxygen into hydrogen streams due to membrane degradation, separator damage, pressure imbalances, or abnormal operating conditions.
The MOD-1040 continuously monitors oxygen concentrations in real time, enabling early detection of crossover events before hazardous gas mixtures develop.
Fast response times below 5 seconds help maximize available Process Safety Time (PST) and provide operators with the information required to prevent equipment damage, maintain hydrogen purity, and protect personnel.
Continuous crossover monitoring also supports predictive maintenance programs by identifying gradual membrane degradation before catastrophic failures occur.
