Formaldehyde Sensor(CH2O Sensor) ME2-CH2O Product Description
-
The ME2-CH2O-Ф16 sensor is a primary battery type electrochemical sensor. CH2O and O2 undergo corresponding oxidation-reduction reactions on the working electrode and counter electrode, releasing charge to form a current. The magnitude of the generated current is proportional to the concentration of CH2O and follows Faraday's law. By measuring the current, the concentration of CH2O can be determined. The ME2-CH2O-Ф16 formaldehyde sensor is a fuel cell type electrochemical sensor. Formaldehyde and oxygen undergo corresponding oxidation-reduction reactions on the working electrode and counter electrode, releasing charge to form a current. The magnitude of the generated current is proportional to the concentration of formaldehyde and follows Faraday's law. By measuring the current, the concentration of formaldehyde can be determined.
