From BlueSens GmbH, the thermal conductivity hydrogen sensor BCP-H2 measures any concentration of hydrogen in the shake flask and fermenter. The BCP-H2 can be integrated directly into the gas line and operates independent from the gas flow. Application areas are the chemical industry, biogas plants, agriculture and the Bioprocessing. It can also be used to monitor algal hydrogen production. The reasonably priced BCP-H2 measures very stable and is highly reliable.
