| Abstract: | Based on the operation and management experience of on-line COD_(Cr) analyzer,several suggestions are put forward,including replacing ferrous ammonium sulfate by potassium hydrogen phthalate as range-measured solution,replacing zero offset by beginning offset,and inspecting the compatibility of analyzer to water quality when the potassium dichromate method is not used. |

| Keywords: | on-line COD_(Cr) analyzer measuring range adjustment solution zero offset potassium dichromate method |
