PINGXUAN PXws-2000 Karl Fischer Moisture Analyzer 1μg-200mg

PXws-2000

Karl Fischer Moisture Analyzer

Large screen LCD display, touch button, Karl Fischer Coulometry measurement, double platinum electrode measurement Voltage, with large current background compensation function, Sensitivity 0.1μg.

The Karl Fischer Moisture Analyzer has a high-current background compensation function that greatly shortens the standby time. The unique reagent failure detection function automatically reminds users to replace failed reagents in time, greatly improving the utilization rate of reagents. Built-in large-capacity memory can store 200 test records, and convenient retrieval method allows users to easily review and print test reports.

The PXWS2000 fully automatic trace moisture analyzer adopts the principle of Karl-Fischer coulomb titration. It has the advantages of high measurement accuracy, good repeatability, and low testing cost, and is widely used in petroleum, chemical industry, electric power, and scientific research.

Main features

• Simple operation

The PXWS2000 fully automatic trace moisture analyzer uses a 5.7-inch large-screen LCD display and user-friendly menu settings to facilitate user operation. The instrument program contains all operations, formulas, calculations, reports, etc. in relevant standards such as GB7600-87 "Method for determination of moisture content of transformer oil in operation" (Coulomb method). With just one click, the test is completed automatically, report values ​​are automatically displayed and printed.

• Humanized appearance design

The instrument adopts humanized appearance design. The height and width of the instrument are in line with the operator's habits. The electrolytic cell is located on the upper right side of the instrument and the buttons are located on the left side of the instrument. When injecting samples with your right hand, just press your left thumb and the instrument will automatically complete all test analysis and output the results.

• Blank current automatically deducted

Different environmental humidity will affect the state of the reagents in the electrolytic cell. The ZTWS series trace moisture analyzer can automatically deduct this part of the blank current, thereby ensuring the test accuracy of the instrument under different test conditions.

• Visual indication of reagent consumption and reagent failure reminder function

The consumption of reagents and when to judge that the reagent has expired are issues that need to be paid attention to when using the Karl Fischer Coulometric Moisture Analyzer, because when the reagent expires, the measured data has no practical significance. In many cases, fluctuations in measurement Voltage do not mean that the reagent has failed. After the user replaces a new reagent, he can enter the reagent life menu and set the preset value. Whether it is pre-titration before analysis or during normal analysis operations in the future, the consumption of reagents will always be monitored and recorded at any time. When the reagents expire, the instrument will sound an alarm to remind the user.

• After the test is completed, the instrument automatically deducts the blank current value, and the displayed value is the actual moisture content in the sample.

• Excellent technology

1. It adopts a powerful microprocessor, dual CPU design, and full Chinese interactive menu.

2. Dual power channels separate the electrolysis electrode and the measurement electrode, and the instrument can automatically suppress various interferences, greatly improving the accuracy of the test results.

3. The measured electrode data is directly A/D sampled and converted, and the true value of the measured data eliminates errors caused in the analog circuit, making the test results more accurate.

4. After the test is completed, the instrument can automatically store historical data according to the formula selected by the user. The historical records can be browsed, queried and printed by the user at will, and 200 records can be stored.

5. The instrument software is equipped with complete calculation formulas and can automatically calculate according to user settings.

6. The measuring electrode fault diagnosis program detects at any time and prompts the user if any abnormalities are found.

•  Self-test function

If there is a short circuit or open circuit failure in the electrode, the instrument will automatically prompt the user.

• Speed ​​adjustment

The stirring speed regulating potentiometer is installed behind the operation panel, and the user can adjust it conveniently.

• End point display

The buzzer sounds, Chinese characters prompt, and the measurement results are displayed intuitively.

• automatic date

The year, month, day, day of the week, hour, minute and second are automatically stored after power failure and will not be lost. 

Can be used to accurately measure trace amounts of moisture in various liquids, solids and gases.
