| other | Abnormal alarm and power failure will not lose data; touch screen display and command input; After abnormal reset and power failure, the instrument automatically discharges the residual reactant in the device and automatically restores the working state |
A mixture of water sample, potassium dichromate digestion solution, silver sulfate solution (silver sulfate as a catalyst can oxidize linear aliphatic compounds more efficiently), and concentrated sulfuric acid heated to 165°C, the dichromate ion oxidation solution The color of organic matter will change, the analyzer detects the color change, and converts this change into COD value and outputs it. The amount of dichromate ions consumed corresponds to the amount of oxidizable organic matter.
