The YMHN-50 can generate a hydrogen-nitrogen gas blend (below, "hydrogen trace gas") from just an injection of purified water, and is also capable of generating hydrogen trace gas easily and economically.

*Trace gas: Very small quantities of a gas that, in product airtightness investigations and testing, is mainly used to detect leakages in test subjects.


  • Generates hydrogen from purified water and extracts nitrogen from air, then blends them precisely to produce hydrogen trace gas.
  • Highly reliable safety system emits no flammable hydrogen gas.
  • Under Japanese law, no legal applications need to be submitted for installation and the system can be installed smoothly into a production line.

Product name: Hydrogen trace gas generator
Model number: YMHN-50
Starting date of order acceptance: March 2 (Monday)
Scheduled number of sales in the first year (domestic, overseas): 5 units in total
