Product Description Product DescriptionKarl Fischer Water Content Tester for Liquids ,Solids and GasesThe Karl Fischer titration instrument is a specialized analytical instrument used to determine the moisture content in samples. Its principle is based on the Karl Fischer reaction, which involves the quantitative reaction of iodine and sulfur dioxide with water in the presence of pyridine and methanol. The moisture content in the sample is calculated by measuring the amount of iodine consumed in the reaction.(1) Large pool bottle (anode chamber) (2) Measuring electrode (3) Drying tube (4) Electrolytic electrode (cathode chamber)(5) injection plug (6) magnetic stir bar (7) electrolytic cell sealing plug Main technical features* Intelligent Determination of water content testerPowerful new-generation processor; dual-CPU design.Dual power channels separate electrolytic electrode and measuring electrode; automatically removing all kinds of interference; greatly improving the accuracy of test results.Measuring electrode data directly A / D sample converting; data true value avoids errors caused by analog circuit; results more accurate.* Easy Operation of Moisture MeterTouch-screen operation; only pressing once then the test will be done automatically and the reported values will automatically display.* Background Compensation Large current background compensation. Standby time can be shortened to be less than 10 minutes.* Rotating Speed ControlSoftware adjusting stirring speed; selection between 0 to 36.* End Point IndicationCharacter tips and buzzer* Perfect Calculating Function of Karl Fischer moisture meterAutomatically display, calculate, print ug / ppm / percentages / mg/L / sample name / test date etc.* Automatic Date Data StorageYear, month, day, hour, minute, second; automatic storage when power off .Product ParametersDisplayLCDMeasuring range3ug to 200 mg water; Water content range: 1ppm-100%Resolution0.01 ug waterAccuracy10μg-1mg water, ± 0.2%; >1mg water, < ± 0.3% (excluding injection error).Electrolysis speedmax 2.4 mg/minElectrolytic current0~430 mAAmbient temperature5~35 oCHumidity≤85%Dimension and Weight320*240*180mm ; about 6kgThe working principleThe measuring principle used in this instrument is the Karl-Fischer Coulomb method. The principle is based on the fact that when water is present, iodine is reduced by sulphur dioxide, and in the presence of pyridine and methanol, pyridine iodine and methyl pyridine thioate are formed. The reaction formula is:I2+SO2+3C5H5N+H20→2C5H5N·HI+C5H5N·SO3 ......................(1)C5H5N·SO3+CH3OH→C5H5N·HSO4CH3 ....................................(2)During the electrolysis process, the electrode reaction is as follows:Anode: 2I--2e→I2 ...................................................................................(3)Cathode: 2H++2e→H2↑........................................................................(4)The reagent solution used is a mixture of predominant iodine and pyridine-doped pyridine, methanol, etc., and iodine is formed on the anode by electrolysis, and iodine is reacted with water to form hydroiodic acid until all the water has been reacted. The end of the reaction was detected with a platinum electrode.According to Faraday's law, the formula for calculating the moisture content in the sample is obtained:Where:W - moisture content in the sample, in microgramsQ--Electrolysis power, unit: millicoulombCalculated by the instrument, the moisture content of the tested sample is directly displayed on the display. The instrument uses an electrolysis current automatic control system. The size of the electrolysis current can be determined according to the moisture content of the sample, up to 430 mA.Detailed PhotosAfter Sales ServiceServiceDevice Problem HandlingSocial media 24 hours online communicationMail Seamless DockingVideo ConferencingRelated porductContact usIf you have any questions about this Moisture Meter Karl Fischer Water Content Tester for Liquids ,Solids and Gases or the instruction, please contact us in time.
