ME3-CH2O formaldehyde gas sensor
ME3-CH2O formaldehyde sensor is a constant-potential electrolytic sensor. Formaldehyde and oxygen undergo a corresponding redox reaction 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. By testing the size of the current The level of formaldehyde concentration can be determined.
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 in industrial and environmental protection fields.
