    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.
