Adjoint automatic monitoring device and method for deposition rate of salt mist

An automatic monitoring device for a deposition rate of salt mist, comprising a wet candle method-based salt mist deposition rate acquisition unit, a single chip, a digital-to-analog (D/A) conversion circuit, and a data acquisition module;

• wherein the single chip is connected to the D/A conversion circuit;
• the D/A conversion circuit is connected to the wet candle method-based salt mist deposition rate acquisition unit;
• the single chip is configured to send a digital signal instruction;
• the D/A conversion circuit is configured to convert the digital signal instruction into an analog signal instruction and send the analog signal instruction to the wet candle method-based salt mist deposition rate acquisition unit;
• the data acquisition module is connected to a chloride ion selective electrode of the wet candle method-based salt mist deposition rate acquisition unit and the single chip separately;
• the data acquisition module is configured to acquire a current value and a liquid level height variation of a solution in a trapping pool output by the wet candle method-based salt mist deposition rate acquisition unit;
• and the single chip is configured to calculate a deposition rate of salt mist based on the current value and the liquid level height variation.
