🔬 How It Works? ⚗️
The AE-KFT-40VC operates on the Karl Fischer reaction, where iodine reacts quantitatively with water in the sample. The titrator uses either volumetric titration—adding a titrant of known concentration—or coulometric titration—generating titrant electrochemically—to measure water content precisely. The built-in electrodes detect the endpoint, while the LCD screen displays real-time titration curves and results, ensuring accuracy and ease of operation.
