Modcon Systems’ MOD-1040 In-Situ Oxygen Analyzer provides fast, direct oxygen measurement for hydrogen and other demanding process gas applications. Using optical technology, it measures from 1 ppm to 100% O₂, operates at pressures up to 350 barg, and delivers T90 response below 5 seconds. By measuring directly in the process, the MOD-1040 can reduce the need for complex sample extraction and conditioning systems, improving response time while reducing maintenance and potential leak points. The analyzer is ATEX/IECEx Zone 1 and SIL 2 certified, with automatic pressure and temperature compensation for changing process conditions.
London, United Kingdom, 9th Sep 2026 – Modcon Systems Ltd., a developer of advanced process analyzers and industrial optimization technologies, is advancing oxygen measurement for hydrogen, natural gas, refining and other process industries with its MOD-1040 In-Situ Optical Oxygen Analyzer.
The MOD-1040 is designed to measure oxygen directly at the process measurement point, reducing the need for conventional sample extraction and conditioning systems. This approach can provide faster visibility of changing oxygen concentrations while reducing sample tubing, pressure regulators, filters and other components associated with extractive analyzer systems.
Using optical luminescence-quenching technology, the MOD-1040 provides continuous oxygen measurement from 1 ppm to 100% O₂, operates at process pressures up to 350 barg (5,076 psi) and provides a T90 response time of less than five seconds.
Addressing the Challenges of Hydrogen Measurement
Fast and reliable oxygen measurement is particularly important in hydrogen production, compression, storage and transportation. Oxygen contamination can affect hydrogen purity and, at elevated concentrations, become a significant process safety concern.
In electrolyzer applications, monitoring oxygen in the hydrogen stream can also provide early indication of abnormal gas crossover conditions.
Traditional extractive analyzer systems typically remove a gas sample from the process, reduce its pressure and transport it to an analyzer. For high-pressure hydrogen applications, this may require additional tubing, regulators, valves and sample handling equipment.
The MOD-1040 enables oxygen measurement directly at process pressure, simplifying the measurement architecture and reducing sample transport delays and potential leak points.
Automatic Compensation for Process Conditions
Direct process measurement requires the analyzer to account for changing operating conditions. The latest MOD-1040 design supports automatic pressure and temperature compensation, using external process signals to correct the oxygen measurement as operating conditions change.
The analyzer also provides Modbus RTU communication and Bluetooth connectivity for commissioning, calibration and diagnostics.
Different wetted-material configurations are available for demanding process environments, including 316/316L stainless steel, Nickel 200/201, Inconel 625 and Hastelloy C276.
Designed for Hazardous Process Applications
The MOD-1040 is ATEX, ECASEx and IECEx certified for Zone 1 hazardous areas and SIL 2 certified, supporting its use in critical hydrogen, hydrocarbon and industrial gas applications.
Beyond hydrogen, the analyzer can be applied to natural gas, refinery and petrochemical gases, flare gas, biogas, renewable natural gas and industrial gas production, where rapid detection of oxygen can support process control, gas quality and operational safety.
Moving Oxygen Measurement Closer to the Process
As industrial plants increasingly rely on real-time process data for automation, safety systems, digital twins and Industrial AI, the speed and quality of measurement are becoming increasingly important.
The MOD-1040 reflects Modcon’s approach of moving analysis closer to the process itself. Rather than bringing the process sample to the analyzer, the analyzer is brought directly to the process.
