Ideal for continuous automatic measurement of chemical oxygen demand, an indicator of pollution!
The "COD Automatic Analyzer" is an automated system that complies with the "JIS-K0102 Factory Wastewater Testing Method." When the measurement start time arrives (with various settings pre-configured for auto mode), it measures and injects specified amounts of sample water, dilution water, and reagents (sulfuric acid, potassium permanganate for non-silver added, and silver nitrate, sulfuric acid, potassium permanganate for silver added) and then heats the mixture in an oil bath at 100 degrees Celsius for 30 minutes to oxidize the oxidizable substances in the sample. 【Features】 ○ Continuous automatic measurement device for Chemical Oxygen Demand (COD), an indicator of pollution in rivers and factory wastewater. ○ Ideal for managing and controlling water treatment, managing freshwater environments, and regulating overall water quality.
