Revolutionary precision in hydrogen concentration measurement: Discover our gas measuring devices with industry-leading response time of 30 ms and a measurement range from a few ppm to 100 vol%, specially developed for the new requirements of the hydrogen infrastructure in the energy sector and process industry.

  2. Unrivalled robustness for demanding environments: Our devices resist condensate and water without damage, provide precise measurements up to a pressure of 700 bar, and are optimized for use in humid environments – ideal for electrolysers, fuel cells, and other hydrogen applications.

  3. Maximum safety, minimal maintenance: Increase your work safety with our fast and reliable explosion level monitoring. Our devices are a long-term investment with a lifespan of up to 10 years.

  4. Adaptability meets economy: Save costs and space with our versatile gas measuring devices that can measure a wide variety of gas mixtures without additional sample preparation. A cost-efficient solution that surpasses the competition in terms of price and performance.

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 30 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.
