1. Summary:
This instrument applies to the determination of freezing point of jet fuel in the range of -80~20℃and the flow point of petroleum products (not including crude oil) in the range of -57~51℃. Applied standards: SH/T0770-2005 SH/T0771-2005
2. Features:
l 1.10.4" touch screen computer with USB and Ethernet
l 2.Windows operation system with special testing software of freezing point and flow point, which can display real-time parameters like temperature curve and automatically determine test results; Powerful database management function to facilitate the search and printing
l 3.Special Peltier chilling plates are used asthey have high efficiency, low refrigeration temperature, long service life and environment friendly
l4. Micro quantity of sample results in fast test speed, high accuracy, good repeatability and convenience in cleaning
l 5.CCD image recognition technique is usedto automatically determine the flow point of oil
l6. Photoelectric technique is used to capture the freezing point of the oil.
l7. Key components like temperature sensor, electromagnetic valve and Peltier are all imported and are high reliable
l 8.Single-key operation method achieves automation during the whole testing process
l9. The test result is in the format of standard XML, which can be sent directly to LIMS system of the chemical laboratory
