Toxic Gas Sensor
Application:
Widely suitable for the detection of benzene in industrial and environmental protection fieldsProduct characteristics:
Low power consumptionDescription
The MQ-E3-C6H6 benzene sensor is a constant-potential electrolytic sensor. Benzene and oxygen undergo a corresponding redox reaction at the working and counter electrodes, releasing charge and generating an electric current. The magnitude of the generated current is proportional to the benzene concentration. The benzene concentration can be determined by measuring the current.
