Instrument usage:

The trace moisture analyzer uses the Karl Fischer Coulomb method (also known as the coulometric method), which is internationally recognized as the most accurate moisture determination method and is suitable for the determination of moisture in most liquids, gases, and solids. This instrument uses internationally renowned brand integrated circuits, equipped with a high-resolution 5-inch color touch screen, Chinese character display, automatic calculation of results, easy operation, and accurate testing, making it an ideal choice in the field of moisture detection. This instrument is innovative in technology, easy to operate, fast in experiments, reliable in results, and stable in performance. It is widely used in industries such as petroleum, chemical industry, electricity, medicine, pesticides, minerals, batteries, plastics, refrigeration, machinery, electronics, and research institutes.
