Instrument introduction:
The fully automatic micro-pour point, cloud point, and freezing point tester is designed and manufactured in accordance with standards ASTM D6749, ASTM D7683, and ASTM D8615. It is suitable for the determination of pour point, cloud point, and freezing point of petroleum products and aviation kerosene under these standards.
The fully automatic micro-dip point, cloud point, and freezing point tester is a fully automated instrument controlled by a PLC. Its operation is extremely simple. Users simply need to load the oil sample to be tested into a glass test cup, turn on the power switch, and press a button to start the test. The system will automatically carry out the test according to the user-selected test procedure. The instrument also features a self-checking function, which is executed first every time the test is initiated.
This instrument features a fully English-language interface. The turbidity and freezing points are detected using coaxial fiber optics, while the pour point is measured using the pneumatic method, ensuring higher accuracy. Upon completion of the measurement, the system will emit an audible alert, lock the display, and automatically save the measurement results.
Instrument features:
◇ Accurate and sensitive automatic detection of pour point, cloud point, and freezing point
◇ Fully automated testing process, with minimal sample usage and simple operation
◇ The turbidity and freezing points are detected using optical fiber, while the pour point is detected using the pneumatic method, achieving higher accuracy
◇ The refrigeration system is safe and environmentally friendly, as the metal bath does not require liquid refrigerant
◇ Ultra-fast cooling speed, with the cold bath reaching -90℃ from room temperature in just 15 minutes
◇ Ultra-low refrigeration depth, capable of reaching a refrigeration depth of -95℃
Technical parameters:
◇ Compliant with standards: ASTM D6749-24, ASTM D7683-21, ASTM D8615-26
◇ Detection range: -85℃ to room temperature
◇ Refrigeration depth: -95℃
◇ Sample volume: 4.5mL～5mL
◇ Test cup: Capacity approximately 12mL
◇ Detection method: Pour point: pressure method; cloud point, freezing point: fiber optic
◇ Temperature measurement: Robust metal material and Pt100 probe with built-in calibration program, equipped with 10 calibration points, temperature sensor outer diameter of 2mm, accuracy of 0.1℃, error less than 1%
◇ Detection interval temperature: pour point: 1℃~3℃; cloud point, freezing point: 0.1℃~1℃
◇ Preheating temperature: The sample is automatically preheated to 45℃ or 9℃ above the expected temperature, whichever is higher, but not exceeding 70℃. The bath temperature is maintained at 48℃ or 12℃ above the expected temperature, whichever is higher.
◇ Cooling rate: For metal bath cooling, when the expected temperature is above 40℃, the cooling rate should be 3℃ to 4℃ per minute; when the expected temperature is below 40℃, the cooling rate should be 0.8℃ to 1.1℃ per minute.
◇ End of heating: After the test is completed, the temperature will automatically rise to room temperature and then the heating will automatically stop
◇ Safety: System self-check, fault alarm, and heating cessation when temperature exceeds 70℃.
