Scope
Main technical content: The microcomputer salt content measuring instrument is suitable for measuring the salt content in crude oil and its products, referring to the content of water-soluble chloride salts, including sodium chloride, magnesium chloride, calcium chloride, etc. All of their contents are calculated by converting them into the amount of sodium chloride. The measurement principle is that the sample enters the salt electrolytic cell, and the Cl- in the sample reacts with Ag+ in the electrolyte solution, which reduces the concentration of Ag+ in the solution after the reaction. The reference electrode sends the potential difference caused by the concentration change to the microcoulomb amplifier, and the amplifier outputs a corresponding voltage to the working electrode. The amount of Ag+ needed to replenish the consumption is measured. According to Faraday's law, the Cl- and salt content of the sample can be determined.
