Karl Fischer Titrimetric Moisture Analyzer

The Karl Fischer moisture titrator is based on the chemical principle of the quantitative reaction between iodine and sulfur dioxide in a methanol solution with water. It detects the titration endpoint through electrochemical methods, enabling direct measurement of the moisture content in samples. It is suitable for moisture detection in liquid, solid, and gas samples across industries such as chemicals, pharmaceuticals, and food.
Selection
When selecting, consider matching the sample properties with the reagent type: use volumetric methods for liquid samples and coulometric methods for solid samples. Determine the instrument accuracy based on the moisture content range: choose an accuracy of 0.001g for routine samples, while micro samples require an accuracy of 0.1μg. Select the automation level based on daily testing volume: automatic titration models are suitable for high-frequency testing. Pay attention to the instrument's protective configuration: choose corrosion-resistant models for corrosive environments.
