The AVVOR 9000 heavy metal online monitor can automatically and continuously monitor metal ions in water bodies, and is widely used in industrial production streams, municipal wastewater discharge, rivers and lakes, surface water, groundwater, drinking water, and seawater. By pre-treatment of water samples, interference from organic matter can be effectively eliminated, greatly improving the accuracy and reliability of instrument testing, and truly achieving the warning function of water quality safety.

measuring principle
The AVVOR 9000 heavy metal online monitoring instrument adopts internationally recognized "voltammetry" technology. Firstly, the analytical solution is subjected to pre electrolysis under certain conditions to enrich the metal to be tested on the working electrode. Then, the solution is allowed to precipitate for a period of time, and an electric potential is applied to precipitate the metal to be tested enriched on the working electrode. The concentration of metal ions in the solution is calculated based on the current change and the corresponding electric potential of the metal during the entire process.
