describe

The handheld dissolved oxygen analyzer mainly works based on the principles of fluorescence or electrochemical methods. Fluorescence method: The sensor emits blue light to excite the fluorescent substance, and dissolved oxygen quenches the red light it emits. The oxygen concentration is calculated by detecting changes in fluorescence intensity or lifetime. Electrochemical method: Oxygen molecules are reduced at the cathode through a thin film, generating a current signal proportional to the oxygen concentration. Both methods perform temperature compensation to ensure accurate results.
