KDSZ-803 Automatic acid value measuring instrument for transformer oil, turbine oil value measuring instrument, using microcomputer control, electrical, optical, mechanical, chemical integration automatic design, instead of manual operation, improve the work efficiency, reduce the labor intensity of the staff, reduce the harm of organic solvents and chemicals to the human body. Simple operation, easy to use, strong anti-interference ability, stable and reliable.

1, 320x240 graphic dot matrix LCD display, touch keys, user-friendly interface;
2, the principle of neutralization titration method, the use of computer control at normal temperature automatically complete the liquid, titration, stirring, determination of titration end point, LCD screen display test results and can be printed out;
3, the color sensor with the detection of titration end point, the end condition judgment is reliable;
4, no waste liquid cup, extract liquid and neutralization liquid by peristaltic pump control to add, high measurement accuracy;
5, historical record query, the instrument has automatic memory function for the experimental results, automatically store the historical record with time mark, and the data is not lost after power failure, can be saved for more than 10 years for future query and printing;
6. Calendar clock with temperature compensation, accurate travel time, automatic record of measured date and time, can run for more than 10 years in the state of power failure;
