GD-611 Automatic Aniline Point Apparatus

What is Aniline Point?

The aniline point refers to the low temperature at which the petroleum product is dissolved in an equal volume of aniline. Aniline point is helpful in characterizing pure hydrocarbons and in the analysis of hydrocarbon mixtures, and aniline point is used to evaluate aromatics content in hydrocarbon mixtures.


The automatic aniline point apparatus is designed and made according to GB/T 262 Petroleum Products and Hydrocarbon Solvents - Determination of aniline point and mixed aniline point and ASTM D611 Standard Test Methods for Aniline Point and Mixed Aniline Point of Petroleum Products and Hydrocarbon Solvents. It is suitable for the determination of aniline points in light-colored petroleum products and dark-colored petroleum products.


1.The automatic aniline point apparatus fully controls the test process, just press the start button to start the test.

2.It adopts 7-inch touch-type high-resolution LCD screen display.

3.Equipped with imported photoelectric devices with good repeatability and reproducibility.

4.Unique temperature control mode, divided into rapid heating and program-controlled heating and cooling, and the heating and cooling rate is stable.

5.Microprocessor program control, automatic heating and heating, automatic stirring, automatic cooling, automatic detection and identification, automatic test result storage and printing.

6.Equipped with standard mode and quick mode to choose from. In the standard mode, the validity of multiple results is automatically judged, and there is a clear text indication.
