Description
The ME3-CH20 formaldehyde sensor is a fixed-potential electrolysis sensor. Formaldehyde and oxygen undergo corresponding redox reactions on the working electrode and counter electrode and release charge to form a current. The current generated is proportional to the concentration of formaldehyde. You can determine the level of formaldehyde concentration.
Sensor characteristics: low power consumption, high precision, high sensitivity, wide linear range, strong anti-interference ability, excellent repeatability and stability.
Main application: Widely suitable for the detection of formaldehyde in the field of industry and ball protection.
