The measurement of hydrogen concentration using thermal conductivity offers several advantages

  • Firstly, it enables a fast and accurate determination of hydrogen content in a medium. By utilizing thermal conductivity, precise measurements can be obtained without the need for complex and time-consuming sampling or chemical analyses.
  • Secondly, it enables a fast response time of just 100 ms, allowing for nearly real-time monitoring. This enables quick detection of changes in hydrogen concentration and early identification of potential safety risks.
  • Thirdly, thermal conductivity measurement is a cost-effective solution. The required sensors and devices are typically affordable and easy to operate. Additionally, the method does not require expensive consumables or extensive maintenance.
  • Fourthly, thermal conductivity measurement provides a wide dynamic measurement range. It can detect hydrogen concentrations ranging from a few parts per million (ppm) to 100% volume percent (Vol%). This versatility allows for its application in a variety of scenarios, from monitoring hydrogen leaks in industrial facilities to accurately determining hydrogen concentration in fuel cells.
  • Finally, measuring hydrogen concentration through thermal conductivity allows for continuous monitoring. By employing automated systems, continuous measurements can be performed to capture real-time changes and detect potential safety risks early on.
  • Overall, the measurement of hydrogen concentration using thermal conductivity provides an efficient, accurate, and cost-effective method for monitoring hydrogen in various applications, including industry, energy systems, and environmental protection.

11. August 2023 | Combination of TCD and MEMS technologies: the silver bullet in hydrogen measurement

To be able to use hydrogen safely and on a large scale, high-quality and quantitative production is required on the one hand, and reliable monitoring of the combustion processes on the other. This in turn urgently requires gas measurement systems based on sensors that are particularly sensitive, stable, compact and…


29. Juni 2023 | Revolutionizing Green Transportation With Archigas’ H2 Analysis Technology

Transport accounts for 29% of greenhouse gas emissions in the United States, making it one of the largest contributors, the Environmental Protection Agency reveals. Hydrogen has the power to minimize greenhouse gas emissions in the transport sector, yet hydrogen fuel cell-powered cars aren’t yet commonplace…


20. Juni 2023 | Archigas – New impetus for the energy transition – Technological revolutions tap hydrogen

The green energy transition has finally entered people’s minds: It has been recognized, albeit belatedly, that there is an urgent need to move away from fossil fuels in order to effectively counter climate change with all its negative consequences. Hydrogen (H2) is playing a growing role in this context…
