| description | The utility model discloses a potentiostat. The potentiostat comprises a singlechip processing chip, an on/off control chip and a constant potential control chip, wherein the on/off control chip is used for receiving an on/off signal of the singlechip processing chip and controlling opening and closing of an on/off control switch according to an on/off signal; and the constant potential control chip is connected with a flexible anode through an anode cable via the on/off control switch, is connected with a buried pipeline through a cathode cable and is used for detecting whether the off-potential of the buried pipeline is consistent with a preset cathode protection potential in the off time period and adjusting the off-potential of the buried pipeline to the cathode protection potential under the condition that the off-potential is inconsistent with the cathode protection potential. According to the potentiostat, the influence of IR drop on the cathode protection of the flexible anode can be eliminated, so th |
