For industrial hydrogen monitoring
Application:
For H2 detection in industrial and environmental field.Product characteristics:
Be stable1. Description
MQ-E3-H2 is the sensor of fixed potential electrolysis type. By redox reaction, H₂and O₂release charge and form the current. The value of current is proportional to the concentration of H₂. By testing the value of current, the concentration of H₂ is known.
