CH2O Sensor
Application:
Used for formaldehyde detection in industrial and environmental protection fieldsProduct characteristics:
Low power consumptionDescription
MQ-E3-CH2O formaldehyde sensor is a constant potential electrolytic sensor. Formaldehyde and oxygen undergo corresponding redox reactions on the working electrode and the counter electrode and release charges to form current. The magnitude of the current generated is proportional to the concentration of formaldehyde. The formaldehyde concentration can be determined by testing the magnitude of the current.
