PINGXUAN Karl Fischer Moisture Analyzer pxWS-8A Power titration

Introduction

The whole machine adopts relay-less process design, which avoids hidden dangers caused by oxidation of memory relay contacts and extends the service life of the instrument. The reagent failure detection function automatically reminds users to replace failed , greatly improving the utilization rate of reagents. It is equipped with a printer interface, and users can choose a micro- printer according to their needs to save data. It has been widely used in electric power, petroleum, chemical industry, and other sectors .

The PXWS-8A 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. It is widely used in petroleum, chemical industry, electric power, scientific research and education and other departments. It can be used Accurately measure trace amounts of moisture in a variety of liquids, solids and gases.

Main features

• Simple operation

The PXWS-8A trace moisture analyzer adopts a large-screen LCD display and user-friendly menu settings for easy operation.

• High current background compensation function

A major problem with using existing domestic (CN) micro-water meters is that the waiting time before sample injection testing is too long, sometimes even requiring several hours of waiting, making the test analysis work extremely boring. ZTWS series fully automatic trace moisture analyzer is the first among similar domestic (CN) instruments to introduce a high current background compensation function, which can shorten the standby time to less than 30 minutes.

• 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. Automatically calculate the blank current caused by environmental interference, display and automatically deduct it.

•  Self-test function

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

• End point display

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

• Perpetual calendar

The year, month, day, day of the week, hour, minute and second are automatically stored after a power outage and will not be lost for 10 years.
