Product Features

1. The instrument adopts a fully enclosed titration cell, which can use various Karl Fischer reagents. The system drift is extremely low, and the solvent is automatically replaced and the waste liquid is discharged to avoid the leakage of toxic reagents and the infiltration of environmental moisture; Special nuts and seals are used for pipeline joints.

2. Color LCD touch screen, graphical shortcut key operation is convenient and fast, the test parameter setting method is simple, all analysis results can be stored, and multiple results (moisture content, percentage content, PPM content, Karl Fischer reagent consumption) are displayed simultaneously.

3. The color titration curve is dynamically displayed, and the measurement results are automatically memorized. The measurement results can be output or printed in the format required by GLP/GMP.

4. Carefully designed titration core patented technology, using piston push up burette, significantly reduces instrument failure rate while also achieving titration control accuracy. The patented piston head created by Hegong can perfectly match with high-precision measuring tubes in ambient temperatures between -20 ℃ and 40 ℃, and can achieve blowing to push the piston to move without any reagent leakage. It has also created a lifespan that is up to 5 times longer than the other party.

5. The brand new sealing design of the titration cell not only keeps the system extremely low drift, but also prevents toxic reagents from leaking in the cell, ensuring the safety of operators and the environment. Hegong's original patented technology for adding samples is suitable for adding samples of different forms such as solids, liquids/gases. Optional micro titration cup and maintenance free dual platinum needle electrode.

6. Details determine success or failure, and carefully designed casing seals and leak deflectors may never be needed. Because the possibility of liquid leakage has been reduced to one in ten thousand, however, the unwavering design philosophy is to ensure comprehensive protection. The AKF series Karl Fischer moisture analyzer no longer has the common scenario of similar instrument reagents leaking into the instrument host and corroding the internal components of the host.

7. Fully automatic measurement, advanced endpoint algorithm, can use various domestic and foreign brands of Karl Fischer reagents; The measurement is simple, rapid, and accurate; Automatic tracking of environmental moisture drift, which can be automatically deducted to ensure accurate analysis results;

8. The instrument can achieve functions such as inhalation of reagents, measurement, endpoint display, solvent inhalation, waste liquid discharge, stirring, and stepless speed regulation; Instrument status, metering pump injection volume, current time, drift and other parameters are displayed in real-time.

9. The instrument adjusts the titration speed according to the sample and uses a high-precision titration control system for high detection accuracy; Intelligent fault recognition, automatic shutdown of hardware faults, and protection of important components; The high-precision quantitative tube and anti diffusion titration head using unique patented technology ensure accurate measurement results, stable operation, and extremely low failure rate of the system, and extend the life of key components by more than 5 times.

10. AKF-2010V includes multiple data interfaces: RS-232C connection port, network interface, USB interface; Optional micro data dedicated printer, capable of printing analysis reports at any time. The report data can be exported.

11. The intelligent reagent management system enables automatic addition of fresh reagents in a fully enclosed state, as well as automatic replacement of Karl Fischer reagents and discharge of waste liquids, effectively protecting experimental personnel from direct contact with toxic solvents and preventing overflow of waste liquid bottles.
