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.

working principle

The reagent solution used is a mixture of dominant iodine and arsenic, methanol, etc. filled with sulfur dioxide. 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. Injecting the sample into the electrolyte, the water in the sample participates in the reaction, and the instrument can reflect the consumption of iodine during the reaction process. The consumption of iodine can be proportional to the amount of electricity required to electrolyze the same amount of iodine. By instrument calculation, the measured water content is directly displayed on the LCD monitor.

Main Features

● Dual CPU microcomputer control
The dual power channel separates the electrolysis electrode from the measurement electrode, and the instrument can automatically remove various interferences
The electrolytic cell adopts the latest waterproof sealing design, with short balancing time and longer electrolyte usage time
Direct A/D sampling conversion of electrode data measurement eliminates errors caused by analog circuits in measuring true values
● High current background compensation function, standby time can be shortened by less than 10 minutes
If there is a short circuit or open circuit fault in the measuring electrode, the instrument will automatically prompt an alarm
