Product Introduction

       NDWS-III Micro Moisture Analyzer is an instrument that uses the Karl Fischer coulometric method to determine trace moisture. It is suitable for the determination of moisture in petrochemical products, insulating oil of oil-filled electrical equipment, pharmaceuticals, pesticides, mineral raw materials, lithium battery electrolyte, oil used in refrigeration equipment, gases, and other substances.

       This instrument features a large color LCD screen with a Chinese character interface, making human-machine interaction more intuitive and operation simpler. Compared with similar instruments, it significantly improves testing sensitivity. Additionally, it can save historical test data.

Product Features

1. Capable of microanalysis of low-content samples with high sensitivity.
2. Can store 20,000 test results; uses unique alternating equilibrium isolation detection technology for faster, more accurate, and stable equilibrium detection; the electrolysis circuit employs advanced PWM pulse width modulation technology, greatly reducing overall power consumption.
3. User-friendly human-machine interaction with a touch screen interface.
4. Displays clock (year, month, day, hour, minute, second) with power-off retention.
5. Printer: Embedded thermal printer with 36 characters and Chinese character output; printing is quieter, faster, and clearer.
6. Program-controlled operation allows direct numerical input from the interface to adjust stirring speed.
7. Multiple formula options with automatic unit conversion (μg, mg/L, ppm, %), memorizable.
