Toxic Gas Sensor
Application:
Widely suitable for the detection of trimethylamine in the fields of petroleum, petrochemical, medicine and environmental protectionProduct characteristics:
Low power consumptionDescription
The MQ-E3-C3H9N trimethylamine sensor is a constant-potential electrolytic sensor. Trimethylamine and oxygen undergo a corresponding redox reaction at the working and counter electrodes, releasing charge and generating a current. The magnitude of the generated current is proportional to the trimethylamine concentration. The trimethylamine concentration can be determined by measuring the current.
