Hydrogen Sensor, analyzer and monitor - Aeroqual

Why use a Hydrogen sensor? Hydrogen (H) is the most abundant chemical substance in the universe. However, pure hydrogen gas (H2) is scarce in the Earth’s atmosphere. It is lighter than air and therefore escapes Earth’s gravity easier than other heavier gases. It is typically produced by heating natural gas with steam to form a mixture of hydrogen and carbon monoxide which is then separated. Hydrogen …
