Product details
product details
The electrochemical 4S-CO carbon monoxide gas sensor operates based on the principles of electrochemistry, utilizing the electrochemical oxidation process of the gas under test at the working electrode potential in an electrolytic cell. The current generated by the electrochemical reaction of the gas under test is proportional to its concentration and follows Faraday's law. The concentration of the gas under test can be determined by measuring the magnitude of the current.
Sensor characteristics
Low power consumption, high precision, high sensitivity, wide linear range, strong anti-interference ability, excellent repeatability and stability.
Main applications
Widely applicable for carbon monoxide concentration detection in the industrial field.
