Karl Fischer Coulometric Moisture Titrator

The Karl Fischer moisture titrator is based on the quantitative redox reaction between iodine and sulfur dioxide in samples containing moisture, with the titration endpoint detected electrochemically. It is used to determine the trace moisture content in liquids and solids, and is applied in the chemical, pharmaceutical, and food industries for quality control of raw materials and finished products.
Selection
When selecting, consider matching the sample properties with the reagent type: use volumetric methods for liquid samples, while solid samples require a heating furnace. Choose a measurement range of 0.001% to 0.1% based on the detection accuracy requirements. Pay attention to the convenience of electrode maintenance and the frequency of reagent replacement, and ensure that the environmental humidity is below 70%.
