HZKF-2 Oil Karl Fischer Trace Moisture Analyser-Huazheng Electric Manufacturing (Baoding) Co., Ltd

HZKF-2 Karl Fischer Trace Moisture Analyser

The trace moisture analyzer of our company meets the requirements of GB/T 7600, SH/T 0255, GB/T6283, SH/T 0246 and other method standards. The Karl Fischer (Coulomb) method was adopted to determine the content of trace amounts of moisture in liquids of different properties. The trace moisture analyzer has the advantages of high measurement accuracy, fast speed, stable and reliable measurement data, and is widely used in petroleum, chemical, electric power, environmental protection, medicine and other

departments. It can quickly determine the moisture content of alcohols, oils, lipids, ethers, esters, acids, alkanes, benzenes, amines, organic solvents, pesticides, phenols, pharmaceutical raw materials and other chemical, petroleum, pharmaceutical, pesticide and other products.

Functions and features

The instrument adopts a powerful new generation processor and new peripheral circuits, excellent low power consumption. The measuring electrode signal as the criterion for the end of electrolysis, so its stability, accuracy is the key factor affecting the measurement

accuracy, and the accurate detection of the measuring electrode signal is realized due to the use of advanced devices and methods. Further understanding of the characteristics of the reagent, a new software compensation correction algorithm was proposed, which improved the measurement accuracy. Chinese/English character graphic LCD display, the display interface is intuitive and friendly. Main functions and features:

●adopting high-resolution color 480×272 dot matrix color touchscreen LCD, Chinese man-machine dialog interface;

●The use of switching constant current source electrolysis circuit (patented technology) to reduce the power consumption of the instrument;

● High-precision measurement electrode signal generation and detection circuits make the judgment of the electrolysis end point fast and accurate, and have strong anti-interference ability;

● Two methods are used to correct the measurement results: reagent blanking current compensation and equilibrium point drift compensation;

● Built-in 9 kinds of calculation formulas, which can meet the calculation of moisture content under different measurement conditions;

● One injection can be converted into mg/L, ppm, mg/kg, %, % to reduce the number of measurements and reagent consumption, and the moisture content conversion unit can also be specified;

● Adjustment of samples volume, mass and density adjustment can be carried out during or after the test;

● 9-speed stirring speed adjustment; 9-speed electrolysis gain adjustment;

● Automatic detection and recording of measuring electrode open-circuit fault and short-circuit fault;

● Automatic storage of historical records with time stamps;

● Reserve RS232 and RS485 ports to communicate with the computer
