This instrument is designed and manufactured according to the requirements stipulated in the national standards GB510-83 "Petroleum Products Freezing Point Determination Method" and GB3535 "Petroleum Pour Point Determination Method". It is suitable for the determination of freezing point and pouring point of light oil in refineries, electric power, railroads, shipping, petroleum companies and oil commercial departments.
Technical features:
1. High test precision, short test time, using a small metal cold trap, trace samples, program cooling;
2. The use of graphic dynamic simulation of the working state, screen reproduction of the test process;
3. Real-time tracking of oil temperature changes;
4. The whole process of automatic detection, test results accurate repeatability, stable and reliable, easy to operate, can print the experimental results;
5. LCD display, touch control, easy to use, can be heated to 35 ℃ can also be cooled to -70 ℃;
6. Detection of the tilt frame automatically tilt detection, fully compliant with the standard, the test mode can be selected, can be rapid detection can also be tested according to the normal test
