COD-571 chemical oxygen demand meter

The COD-571 chemical oxygen demand meter abandons the traditional complex and bulky spectroscopic system and uses a new type of LED as the light source, which greatly reduces the size and weight of the measuring equipment. Equipped with a dedicated digestion device, the sealed reflux digestion method can be used to heat and reflux 21 samples at the same time. It is easy to operate, has fast digestion speed, can save a lot of water, electricity and reagents, and reduces secondary pollution. COD-571 is suitable for the environmental protection industry and is convenient for the determination of COD in large quantities of samples.
