Hydrogen analysis, measurement and monitoring
Hydrogen analysis can be performed on different measurement technologies. The different measuring methods have their advantages and disadvantages. The Archigas measuring instruments can be used for all measuring tasks in an electrolyzer due to specially developed microsensors and different designs.
Lower and upper explosion limit (LEL, UEL)
The lower and upper explosion limits enclose the range of explosive mixtures, i.e. the range of the content of flammable substance in the mixture with an oxidizing agent in which an explosion can occur. Lower explosion limit 4.0% by volume (mol%) Upper explosion limit 77.0% by volume (mol-%)
Hydrogen quality with thermal conductivity
Quality measurement of hydrogen is necessary for the entire industry. Continuous online quality measurement enables process monitoring and delivery of high quality hydrogen to the customer. With Archigas equipment the H2 purity can be checked continuously and online up to 5.0
Leak detection and room air monitoring
If a leak occurs in the manufacturing process, hydrogen escapes into the environment. In closed rooms, an explosive mixture can develop. The hydrogen concentration in the room air is monitored. Lower explosion limit 4.0% by volume (vol%)
