Introduction
DH4-HCHO-5 is based on the electrochemical formaldehyde sensor working principle, using the HCHO oxidation reaction occurs in the electrolytic cell electrode, the electrode reaction, the induced current, the induced current and is proportional to the concentration of gas, so as to determine the concentration of analyte. The sensor uses three electrode, reference electrode can be stable sensing electrode and reference electrode electric potential, no current through the voltage stability, to maintain their own, so even if the negative electrode for polarization will not have any effect on the sensing electrode, the three electrode structure has a wide measurement range.
