1、Use 320x240 graphics dot matrix LCD full screen touch button human-machine interface friendly.

2、Using neutralization titration principle the end point of titration was determined by the self - motion at room temperature LCD screen display and print test results.

3、The color sensor matched with detection titration endpoint and the termination condition was reliable.

4、No waste liquid cups.

5、The extraction liquid and neutralization liquid are added by peristaltic pump with high metering precision.

6、Historical record inquiry. The instrument has self-motion memory function for experimental results. Self-motion stores the historical record with time mark and the data is not lost after power failure.

7、The calendar clock with temperature compensation is accurateself-motion records the measured date and time and can run for more than 10 years in the state of power failure.

8、Special reagent bottles are used to hold the extraction solution and neutralization solution. The reagent does not contact with air during use avoiding the influence of solvent volatilization and CO2 in air. Users do not touch solvents by hand reducing the harm of organic solvents and chemicals to the human body.

9、Acid testersimplicity of operator，large screen liquid crystal display、chinese menu selection，csers only need to select menu function，click screen to enter the data，self -motion instrument can complete the whole process of acid value determination.

10、The tester can also select only one sample or continuously test 2-6 samples as needed.

11、RS232 interface is left for easy communication with computer.

12、Thermosensitive micro printer makes printing more beautiful and faster with offline printing function.
