Product Overview
P5530 Automatic Trace Moisture Analyzer is suitable for GB/T7600-1987 "Determination of Moisture Content in Running Transformer Oil (Coulomb Method)", SH/T0255-1992 "Determination of Moisture Content in Additives and Lubricating Oil with Additives (Electricity Method)", SH/T0246-1992 "Determination of Moisture Content in Light Petroleum Products (Electricity Method)", accurately measuring trace moisture in liquids, solids, gases, and used in industries such as power, petroleum, chemical, pharmaceutical, and food. It can quickly determine the moisture content of chemical, petroleum, pharmaceutical, pesticide and other products such as alcohols, oils, lipids, ethers, esters, acids, alkanes, benzenes, amines, organic solvents, pesticides, phenols, and pharmaceutical raw materials.
Principle
Iodine is formed on the anode through electrolysis, and the generated iodine is directly proportional to the amount of charge according to Faraday's law. The number of moles of iodine involved in the reaction is equal to the number of moles of water. Inject the sample into the electrolyte, and the water in the sample participates in the reaction. The instrument can reflect the consumption of iodine during the reaction process, and the consumption of iodine can be calculated based on the amount of electricity required to electrolyze the same amount of iodine. After calculation by the instrument, the measured water content can be directly displayed on the liquid crystal display.
