Working principle

The instrument is in accordance with GB510-83 and GB/T The 3535-83 method requires that when testing the freezing point of petroleum products, the CPU controls the refrigeration system to cool the sample, and the color display shows the status, temperature, set value, and clock. When the sample is cooled to the highest temperature at which it cannot move (freezing point), the display shows the freezing point temperature, a sound prompt is given, and the test results are printed. When testing the pour point of petroleum products, when the sample is cooled to the lowest temperature at which it can flow (pour point), the display shows the pour point temperature, a sound prompt is given, and the test results are printed.
