In the implementation of the present utility model, the circuit designed in this patent is shown in fig. 1, where Vcc1 is the positive power supply and Vcc2 is the negative power supply. The working device is placed into the corrosive liquid while being connected with the bottom of the alloy sheet. If the corrosion is not finished, the circuit is kept to be disconnected, and the corrosion time is continuously recorded; and if the corrosion is finished, the conductive corrosion liquid contacts with the second wire at the bottom of the alloy sheet, the circuit is connected, and the counting is stopped. Programming implementation when the circuit is open, ur=0v, counting starts; when the circuit is on, UR > 0V and counting stops.

The connection of the alloy blocks in the working device of the circuit diagram is shown in fig. 2. The corrosion rate to be measured is the rate at which only one side of the sample is exposed, so the remaining surface is encapsulated with epoxy glue so that it does not contact the corrosive liquid. The lead is led into the bottom of the alloy sheet, then the bottom surface and the side surface are encapsulated by epoxy resin, and then the circuit shown in figure 1 is connected.
