Short summary
In natural hydrogen exploration, locating deep gas seepage is often done by measuring soil gas content. For that purpose, we developed a long-term hydrogen concentration monitoring instrument named MONHyTOR. Our laboratory test demonstrates its accuracy, and field data indicate that hydrogen circulation in the soil depend on soil type, water circulation in the soil, air pressure, and air temperature. MONHyTOR can prove to be a promising tool in the natural hydrogen exploration scene.
