The HSY-2122B Micro Moisture Analyzer (Coulometric Method) features a large LCD color touch screen display with a software interface rich in content and Chinese character prompts for operation, offering flexibility and convenience. In addition to high detection sensitivity, simple operation, fast testing speed, and good repeatability, it also includes functions for storing and printing test results. The sample measurement process is automatically controlled by the instrument, with stirring and measurement completed automatically in about 60 seconds, directly displaying the measurement results. The fully sealed titration cell bottle avoids contact between the reagent and the operator, as well as the influence of environmental humidity. The instrument features a Chinese LCD display and includes automatic calculation and printing functions, capable of printing moisture content, sample number, operator, test date, and other information. The instrument accuracy is as follows: ① When the water content is less than 10 micrograms of water, the measurement error is less than 2 μg water; ② When the water content is between 10 micrograms and 1000 micrograms of water, the measurement error is ≤ 2 μg water; ③ When the water content is above 1000 micrograms, the measurement error is ≤ 0.2% (excluding sampling error).
