HACA-4000
Online COD Analyzer
The permanganate (Mn) COD continuous automatic analyzer, HACA-4000, automates the acidic potassium permanganate method for water quality testing.
It determines COD by measuring the permanganate consumed during oxidation, with the titration endpoint identified by an increase in ORP.
Featuring patented technology and pre-measurement logic for enhanced performance, the HACA-4000 is optimized for water quality TMS applications in compliance with the latest communication standards.
