Product Description
Online COD Water Quality Analyzer Overview
This advanced Chemical Oxygen Demand (COD) analyzer measures oxygen consumption by strong oxidants to determine organic and inorganic reducing substances in water samples. As a critical indicator of water pollution levels, this instrument enables long-term, unattended automatic operation with field-configurable settings.
Application Areas
Suitable for industrial pollution source wastewater discharge, industrial process wastewater monitoring, industrial wastewater treatment plant effluent, and municipal sewage treatment plant operations. Optional preprocessing systems ensure reliable testing across diverse field conditions.
Measurement Technology
Utilizes potassium dichromate oxidation spectrophotometric method. The system heats water samples with potassium dichromate digestion solution, silver sulfate catalyst, and concentrated sulfuric acid to 165°C. Colorimetric changes during oxidation are detected and converted to precise COD values, with consumed dichromate ions directly correlating to oxidizable organic matter concentration.
