Coulombic Water Analysis Instrument

The coulometric moisture analyzer is based on the Karl Fischer reaction, where iodine is electrolyzed to react quantitatively with the moisture in the sample, and the moisture content is calculated by measuring the electricity required for electrolysis. It is used to detect trace moisture in materials such as coatings and inks to ensure stable product quality.
Selection
When selecting, consider the compatibility of the sample properties with the reagent type, ensure the moisture detection range covers your needs, pay attention to the instrument's precision and repeatability metrics, inspect the sealing of the electrolytic cell and the durability of the electrodes, and evaluate the ease of operation and maintenance costs.
