AKF-CH8 Multi-Position Automatic Karl Fischer Moisture Analyzer
Product Introduction
AKF-CH8 Multi-Position Automatic Karl Fischer Moisture Analyzer is a high-precision coulometric Karl Fischer moisture analyzer designed for rapid and reliable water content determination in various solid, liquid and powder samples. Based on the classic Karl Fischer coulometric titration principle, the instrument measures moisture content by generating iodine through electrolysis and accurately calculating the reaction between iodine and water in the sample.
With an 8-position automatic sample turntable, intelligent endpoint detection, automatic analysis process and advanced data management functions, AKF-CH8 improves laboratory efficiency while ensuring excellent measurement accuracy and repeatability.
The automatic Karl Fischer moisture analyzer is widely used for moisture analysis of freeze-dried powders, in vitro diagnostic reagents (IVD), battery cathode and anode materials, separators, plastic pellets, lubricating oils, adhesives, chemicals and other moisture-sensitive materials.

Performance Features

Equipped with an 8-position automatic sample carousel, enabling continuous unattended sample testing and improving laboratory throughput.
• High-precision coulometric Karl Fischer titration technology
Based on the internationally recognized Karl Fischer principle, providing accurate trace moisture measurement from microgram levels.
• Automatic constant current polarization detection
The system automatically adjusts electrolysis current from 10 mA to 400 mA without manual endpoint judgment, ensuring stable and reliable results.
• Wide sample compatibility
Built-in 6 electrolysis modes support different Karl Fischer reagents and adapt to various sample types.
• Intelligent touchscreen operation
Featuring a color touchscreen and digital keyboard interface, providing simple operation and intuitive workflow.
• Automatic calculation and data management
Test results are automatically calculated, stored and searchable. Data can be backed up, exported and printed.
• Flexible analysis parameter settings
Supports customized settings including titration delay, endpoint delay, drift compensation, blank correction and fixed test duration.
• Real-time E-T curve display
Displays titration electrolysis curves during analysis, allowing users to monitor the measurement process visually.
• Long-term stability and low maintenance
One-button operation, automatic analysis and intelligent control reduce operating errors and improve instrument service life.

Working Principle
The AKF-CH8 Automatic Karl Fischer Moisture Analyzer uses the coulometric Karl Fischer titration method to determine water content.
During measurement, iodine is generated electrolytically inside the reaction cell. The generated iodine reacts quantitatively with water contained in the sample according to the Karl Fischer reaction formula. Since the amount of iodine generated is directly proportional to the amount of water present, the instrument calculates the moisture content based on the consumed electrical charge.
The automatic detection system monitors the endpoint through polarization changes and stops electrolysis automatically when all water has reacted, providing accurate and repeatable moisture measurement results.
