COD detector introduction
COD detector introduction
COD detector using open tube heat reflux digestion or digestion method. Using a special oxidizer composed of potassium dichromate and the like, plus a special composite catalyst, heating and digestion at a high temperature (165 ° C), and passing monochromatic light through the solution to partially reduce Cr6 + in the oxidant to Cr3 + and reducing Cr3 + Content The c
COD detector works
COD tester by a dedicated COD host and digester composition. Due to the corrosive nature of the strong oxidizing agent used in the assay, severe inaccuracies can be caused to the instrument and oxidant delivery system by slight inadvertent operation. The instrument can be widely used in environmental protection, scientific research monitoring, production monitoring and other fields, is the ideal instrument for environmental monitoring and control.
