for industry gas monitoring
Application:
Widely used in urban atmospheric environment monitoring,enterprise environment monitoring,factory area unorganized emission of pollution gas monitoringProduct characteristics:
high precisionDescription
MQ-E4-O3 is the sensor of fixed potential electrolysis type. By redox reaction, O3 and O₂release charge and form the current. The value of current is proportional to the concentration of O3 and follow the Faraday’s Law. By testing the value of current, the concentration of O3 is known.
