Through rigorous testing by multiple large enterprises and third-party testing brand enterprises, the AKF series Karl Fischer moisture analyzer from Hegong, as an import substitute brand, has launched a new upgraded model AKF-IS2020C lithium Karl Fischer moisture analyzer. This series of products has undergone dozens of technological improvements, resulting in a comprehensive improvement in performance:

★Even simpler!The touch screen human-machine interface is simple and clear, making it easy for non professionals to operate!

★More efficient!Fast balancing and intelligent detection greatly shorten the standby balancing time of the instrument!

★More precise!Accurate and intelligent electrolysis control technology, with detection accuracy and long-term optimization of analysis time!

★More flexible!Added a universal puncture injection mode while retaining the full effect blowing injection mode!

★More stable!Significantly upgraded temperature and flow control modes, and real-time display of temperature and carrier gas flow!

★More secure!Upgraded safety measures such as abnormal termination, intelligent temperature monitoring, and temperature display in the heat sink!

The AKF-BT2020C Karl Fischer titration instrument can directly add samples to the titration cell to quickly determine the trace moisture content of conventional liquid raw materials such as lithium iron phosphate materials, iron phosphate, lithium cobalt oxide, lithium manganese oxide, lithium nickel oxide, ternary materials and other electrolyte materials. The sample can also be placed in a closed headspace sampling bottle through the supporting equipment Karl Fischer sample evaporator, heated above the boiling point of water, and then carried to the titration cell of the Karl Fischer titration instrument for measurement with the help of an external dry carrier gas (dry nitrogen or air). Since high boiling point substances are difficult to evaporate, they will not be introduced into the titration cell. In this way, Karl Fischer reagents in the titration cell are avoided. Direct contact with insoluble substances and other substances in the sample, except for water, At the same time, it avoids interference from other substances on the Karl Fischer reaction. After years of continuous improvement by Hegong Scientific Instruments, the AKF series Karl Fischer water titrator products with sample evaporators have been widely used in fields such as graphite materials, plastic particles, lubricants, solid drugs, rubber, and oil products, accumulating rich application experience; And it has achieved good application results in many well-known enterprises.
