The acid value measuring instrument adopts the principle of neutralization method. Under the normal temperature condition, the microcomputer control automatically completes liquid addition, agitation, titration and end point jud gment. The touch screen is used to select all the working parameters. The man-machine conversation interface is simple, friendly and easy to operate. The average analysis period of the oil sample is about 2 minutes. They can di splay up to 35 sets of measurement results, and print out a number of parameters related to the measurement.

1. Adopts the principle of neutralization method. , the microcomputer control automatic finish adding liquid, stirring, titration and end point judgment in a normal temperature .
2. With LCD touch-screen, The man-machine dialogue interface is simple and friendly, easy to operate, and the average analysis cycle of oil samples is about 2 minutes.
3. Possible to display 35 groups test result, and several parameters related to the measurement can be printed out.
4. Special reagent bottles are used to contain the extraction solution and neutralization solution.The extracted liquid is stored in glass container to avoid plastic additive pollutant. The neutralization solution is stored in polyethylene plastic bottles to completely avoid the possibility of caustic potash reaction with glass.
5. No need to touch the organic solvent with hands,reduces the harm of chemicals to human body.
6. 1~3 samples can be determined respectively.
