The HSY-2122A Micro Moisture Analyzer (Coulometric Method) operates based on the Karl Fischer titration principle and utilizes microcomputer circuitry to measure trace moisture content in various liquids and solids. For solids insoluble in the reagent, substances that react chemically with the reagent, or materials prone to electrode contamination, corresponding solid or liquid sample injectors can be used for indirect measurement. This instrument offers high measurement accuracy, fast analysis speed, wide applicability, stability, reliability, and ease of operation. It is widely used in industries such as power, petroleum, chemical, pesticide, and pharmaceuticals. The sample measurement process is automatically controlled by the instrument, with stirring and measurement completed in approximately 60 seconds, and results displayed directly. The fully sealed titration cell bottle prevents reagent contact with humans and avoids environmental humidity effects.
