This instrument adopts the Karl Fischer volumetric method principle and complies with the GB/T 11133 Liquid Petroleum Product Water Content Determination Karl Fischer Method, GB/T 6283 Chemical Product Moisture Determination Karl Fischer Method, Chinese Pharmacopoeia Moisture Determination Method I, Karl Fischer Method and other method standards.
Main functions:
- Using STM microchip processor control, automatic intelligent analysis and determination of moisture content.
- Two large color Chinese touch LCD screens (resolution 1024 * 600 pixels) display.
- The surface is treated with electrostatic spraying, which is corrosion-resistant and easy to clean;
- Practical auxiliary functions that can connect the “electronic balance” with instrument data communication and processing; (Alternative).
5. Instruments automatically absorb and discharge liquid, greatly reducing manual measurement errors.
6. Powerful storage functions, automatic storage of 1000 measurement results, and easy access to historical records at any time.
7. Instruments automatically measure samples, display analysis results, and calculate the average value of multiple sample measurements.
- Automatically calculate and print ug/ppm/percentage content/mg/L/sample name/experimental date, etc.
- Instrument program can be upgraded when national standards are revised.
