Hydrogen is expected as a clean energy for the realization of a carbon-free society. We are contributing to the building of a hydrogen society through various products.
Nissha FIS, Inc., a Nissha Company, is working on highly sensitive, highly accurate gas sensors, providing SGC (Sensor Gas Chromatograph) that measures even low concentrations of hydrogen in gas samples and hydrogen detectors that detect gas leaks.

A hydrogen detector is a device for detecting hydrogen gas leaks. Hydrogen is a type of flammable gas that can catch fire if its concentration exceeds a certain level. The UN-R134-00-S02 international standard requires fuel cell vehicles to have a device for detecting hydrogen leaks installed. Hydrogen detectors are expected to be used more and more, not just in fuel cell vehicles, but in fuel cell systems for the home or infrastructure such as hydrogen pipelines and hydrogen stations.

• Starts up fast and can respond rapidly
• Detects hydrogen accurately without being affected by other gases
• Durable

The SGC (Sensor Gas Chromatograph) is a gas analyzer that measures even low concentrations of hydrogen within a sample gas. Hydrogen molecules are characterized by their extremely small size and by the fact that they weaken metal they are absorbed into.
Using an SGC (Sensor Gas Chromatograph) helps analyze hydrogen brittleness in research institutes or plants manufacturing materials required for infrastructure such as hydrogen stations.

*Hydrogen brittleness refers to the drop in robustness of metal materials when hydrogen molecules are absorbed into the metal.

• Allows gas analysis at atmospheric pressure
• Very sensitive to even minute amounts of hydrogen
• Allows analysis over a wide temperature range
