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.

03. November 2023 | Archigas landed on the podium of the “Hessen Champions 2023” as a finalist!

More than 60 companies competed for the prestigious German award in three categories. The prizes were presented to the winner and the two co-finalists in the “Innovation” category, including Archigas, by Hesse’s Economics Minister Tarek Al-Wazir. Archigas GmbH made it into the top three in its category thanks to its new, unique semiconductor-based sensor technology for particularly fast, precise, reliable and cost-effective hydrogen measurement…


26. September 2023 | Hochschule RheinMain bestätigt Feuchtigkeitresistenz von H2-Sensor

Das hessische Start-up Archigas hat einen Sensor entwickelt, der auch in einem feuchtem Umfeld Daten messen und übertragen kann. Die Feuchtigkeitresistenz des Sensors wurde nun im Wasserstofflabor der Hochschule Rhein-Main bestätigt. In mehreren Tests konnte die Firma Archigas aus Rüsselsheim am Main nach eigenen Angaben belegen…


22. September 2023 | No More Sweating-H2 Measurement Even In Heavy Wetness!

Tests prove high moisture resistance of Archigas hydrogen sensors. Russelsheim am Main— Dry realization: Only reliable gas analysis makes the production, storage and use of hydrogen as an energy carrier truly safe. So here, you literally must not break out in sweat, for example if the H2 sensor comes into contact with condensation water…
