Water content testing  in Insulating Liquids by Coulometric Karl Fischer Titration

The instrument is designed and made as per national standard of China GB/T 7600 Standard Test Method for Water Content of Transformer Oil in Service (Coulometric Method), industrial standard of China SH/T0246 Standard Test Method for Water Content of Light Oils (Coulometry). ASTM D1533 Standard Test Method for Water in Insulating Liquids by Coulometric Karl Fischer Titration and ASTM D6304 Standard Test Method for Determination of Water in Petroleum Products,Lubricating Oils and Additives by Karl Fischer Titration. It is used to determine water content in the liquid petroleum products.
The instrument adopts microcomputer control technology, with the characteristics of fast analysis speed, high precision, LCD display, automatic printing, menu selection and other functions; It is a fully functional, easy to operate, automatic measuring and analyzing instrument.

1. 1. It can be used for micro analysis of low content samples with high sensitivity.
2. The imported 0.5ul injector for calibration is equipped, and the calibration of the instrument is fast and accurate.
3. It can store 20000 experimental results, easy to query.
4. The unique alternating balance isolation detection technology makes the balance detection more rapid, accurate and stable.
5. The electrolysis circuit adopts advanced PWM pulse width modulation technology, which greatly reduces the power consumption of the whole machine.
6. Friendly man-machine dialogue, with touch screen man-machine interactive interface.
7. Display the clock (year, month, day, hour, minute and second) and keep it when power down.
8. Printer: embedded thermal printer, 36 characters, Chinese characters output, Printing is quieter, faster and clearer.
9. Program control is adopted to adjust the mixing speed by inputting numbers directly from the interface.
10. Multiple formula selection, automatic change of display units (ug, mg / L, ppm,%) can be memorized.
