Product Description Product DescriptionIntroduction:* The Automatic karl fischer titrator determines low concentrations of water in a wide range of liquid, gas and powder samples. The Coulometric Karl Fisher Titrator is used for assessing water content in petroleum and petrochemical products including oils, gasolines, solvents, and fluids as well as other products such as pharmaceuticals and cosmetics.* The Coulometric Karl Fischer titration is the ideal method to determine low moisture and water contents in samples (0.001 to 1% water content).* Karl Fischer Coulometric titrator for measuring trace moisture content in the sample accurately, this method has widely used with the advantages of high accuracy, low test cost. The instrument is based on Karl Fischer Coulometric titrator principle, accurate determination of liquids, solids, gases trace moisture .Product Parameter:1. Electrolytic current: 400mA maximum2.

Weight: 6kgPrincipleKarl Flscher reagent reacts with water below:12 + SO2 + 3C5H5N + CH3OH + H2O = 2C5H5N·HI + C5H5N·HSO4CH3The reagent solution used is prepared by mixing simple substance iodine, I- and SO2-containing methanol, etc. The measurement is based on the conductibility of the equilibrium system consisting of simple substance iodine andI-. The following reactions proceed alternately on two electrodes when the current is imposed on them:2I--2e→I2I2 + 2e→2I-There is an excess of I- in the solution, but the I- concentration change does not greatly affect the solution conductibility. The change of simple substance iodine concentration within a range will cause an effective change of the solution conductibility. We select the range in which the higher simple substance iodine concentration leads to the bigger change of solution conductibility, and measure the value of the current intensity generated by the voltage at both ends of the platinum electrode immersed in the solution. The current intensity reflects the solution conductibility. A sample is injected to the electrolyte. The water in the sample reacts. The tester can detect the iodine change in the reaction, while the tester can calculate the iodine consumption from the electric quantity consumed when the same amount of iodine is electrolyzed out. The mass of the water to be tested is directly indicated on the LED display. This tester has an electrolytic current autocontrol system, which can automatically control the electrolytic current according to the water content of the sample. The maximum electrolytic current is up to 400 mA. During electrolysis, the water content gradually reduces, and the electrolysis rate reduced proportionally till an equilibrium point. The corresponding control loop of end point of titration starts, and the tester stops of measurement accumulation. This system ensures high analysis precision, sensitivity and speed. In addition, some interference factors unavoidably exist during measurement. For example, blank current is generated in the titration cell because of the water immersed in air. However, this tester has the memory and subtracts blank current, so the mass displayed on LED display is the real water content of the sample.Features1.Strong environmental adaptability, precise, accurate and stable measurement results2.Built-in multiple test methods, easier testing3.High reliability4.Simple operation5.The display content is rich, and the measurement process is clear at a glance6.Multiple test result units are optional, suitable for different samples7.Navigational operation, more intuitive and convenient8.Rich extension interfacePackagingContact us!1With competitive price2Premium quality with CE & ISO certification3Strong product OEM & ODM customization capability4Promise production & on-time delivery5Perfect after-sales service, free product accessories615 years of experience in R&D and productionWelcome to contact us talk about details if you are interested in Automatic ASTM D1533 D6304 Karl Fischer Kf Coulometric Titrator Moisture Analyzer.If you want to know more information,Don't hesitation, welcome your inquiry!Price can be negotiated !
