    FAQ
    ❯

    A hydrogen sensor is an electrochemical or catalytic device used to detect the presence and concentration of hydrogen (H₂) in the air. It provides fast and reliable signal output, ensuring safety in industrial and laboratory environments.

    ❯

    The gas sensor measures hydrogen concentration through electrochemical reactions on its electrode surface, generating a weak current proportional to gas concentration. This signal is then converted into readable ppm values.

    ❯

    The h2 gas sensor enable early detection of hydrogen leaks, prevent explosion incidents, and maintain high accuracy, rapid response, and long-term stability even in harsh industrial environments.
