Environmental Product

【 Water test board 】

When it comes in contact with Hydrogen, the sheet changes to colorless/clear within 3 seconds!
And since it reverts back to the original metallic color when there is no more Hydrogen, the sheet can be used over and over again!
Please refer to the list of performance and style for reusing conditions.

アツミテック To achieve an eco-friendly, hydrogen energy environment, members from academia, government and industry came together to establish the "Fukuoka Hydrogen Energy Plan Conference." The result of this project was the implementation of the Visible Hydrogen Sheet.

Product Features

  • Contact with Hydrogen gas changes the product from a metallic color to colorless & transparent.
  • When the Hydrogen gas is removed, it has the properties to revert back to a metallic color, and can be used repeatedly.
  • It can be utilized to confirm the presence of Hydrogen gas, or to check for leaks in connection areas.
  • It detects Hydrogen gas without external power.
  • The product’s flexibility and ability to be cut to size allows the freedom for its use in any desired shape.

Product Structure

As shown in the image below, on top of a transparent PET film, there is a thin membrane made up of a special alloy. It reacts only to hydrogen gas. When hydrogen gas flows in, this thin alloy layer captures the hydrogen and becomes transparent, indicating the presence of hydrogen. A protective topcoat is applied so it is still possible to directly touch the surface of the film, without a drop in functionality.
