Introduction
COD-571 Chemical Oxygen Demand Meter abandons the traditional complex and cumbersome optical splitting system and uses a new LED as the light source, which greatly reduces the size and weight of the measurement equipment. Equipped with a special digestion device, the sealed reflux digestion method can be used to heat and reflux 21 samples at the same time, which is convenient to operate, fast digestion speed, can save a lot of water, electricity and reagents, and reduce secondary pollution. COD-571 is suitable for environmental protection industry and is convenient for the determination of COD in large quantities of samples.
