Auxiliary device prepared for metal nanoprobe

The invention relates to an auxiliary device prepared for a metal nanoprobe, especially relates to an automatic, real-time monitoring, and automatic sound reminding device which assists the preparation of the nanoprobe, and belongs to the field of a condensed matter physics experimental scientific instrument. The auxiliary device comprises an electrolytic tank using a probe body as an anode and apower source; the power source is connected with the electrolytic tank and formed to be an electrolytic loop; the power source comprises a response mechanism, an amplifying circuit and a comparison circuit; the amplifying circuit and the comparison circuit are electrically connected with the response mechanism, and the amplifying circuit is used for amplifying the current in the electrolytic circuit to start the response mechanism; the comparative compares the setting value with the current in the electrolytic circuit to stop or open the response mechanism; the auxiliary device can start by one button in the full proc
