ME2-CH2O-16×15 formaldehyde sensor
The ME2-CH2O-16×15 formaldehyde sensor is a fuel cell electrochemical sensor. Formaldehyde and oxygen undergo corresponding redox reactions on the working electrode and the counter electrode and release charges to form a current. The generated current is proportional to the concentration of formaldehyde. Following Faraday's law, the level of formaldehyde concentration can be determined by testing the magnitude of the current.
Sensor Features
Low power consumption, high precision, high sensitivity, wide linear range, strong anti-interference ability, excellent repeatability and stability.
main application
It is widely suitable for the detection of formaldehyde gas concentration in civil, industrial and environmental protection.
