H2 3E 1% Electrochemical Hydrogen Sensor For Industrial Production Lines Involving Hydrogen - Related Processes
Features:
- Stable detection performance: The 3 - electrode structure maintains a stable potential reference, ensuring a fixed output relative to the sensing electrode and reducing baseline drift. It also has no sensitivity to changes in atmospheric pressure.
- Humidity - resistant design: The sensor has no performance degradation caused by humidity within the operating humidity range, which adapts to various humid working environments.
- Easy integration: As a standard 4 - series size sensor, it can be directly integrated into mainstream gas detector circuit boards and OEM devices without complex structural modifications.
- Cost - effective long - term use: With a service life of more than 2 years and a low monthly sensitivity drift rate, it reduces the frequency of sensor replacement and long - term use costs.
Application Scenarios:
- Hydrogen leak detection devices for industrial production lines involving hydrogen - related processes.
- Concentration monitoring equipment in hydrogen energy storage systems and fuel cell - related facilities.
- Portable gas detectors used in confined spaces where hydrogen may accumulate.
- Safety monitoring modules for electronic equipment and power systems that use hydrogen as a cooling or reaction medium.
