Intelligent intergranular corrosion device

The invention relates to an intelligent intergranular corrosion device which comprises a corrosion device with an electric furnace. A condenser pipe is arranged at the upper end of the corrosion device and is inserted into a rubber ring on the top part of the corrosion device; water circularly flows between the condenser pipe and a cooling water pond through a first water inlet cooling water pipeand a first water outlet cooling water pipe arranged on the left side and the right side of the condenser pipe; the first water inlet cooling water pipe is further connected with a liquid level indicator on the other side; a second water outlet cooling water pipe extends out from the other end of the liquid level indicator; water circularly flows between the liquid level indicator and the coolingwater pond through the first water inlet cooling water pipe and the second water outlet cooling water pipe; the circulation between the liquid level indicator and the cooling water pond is synchronousto the circulation between
