Standard
1. GB/T510 "Test Methods for Solidifying Point of Petroleum Products"
2. GB/T3535 "Test Methods for Pour Point of Petroleum Products"
3. ASTM D97-12 Standard Test Method for Pour Point of Petroleum Products
It is suitable to determine solidifying point and pour point of transformer oil and other light oils.
Characteristics
1. It adopts single chip microcomputer to be the core of calculation and control,having man-machine dialog interface and menu prompt input functions. Operator can compile real-time application software according to oil temperature changes.
2. It adopts LCD screen to track and display the state of oil temperature changes. The diagram shows dynamic stimulative working process.
3. It adopts high accuracy sensor and semiconductor refrigeration. The cooling rate is fast and test precision is high. The results are reliable.
4. The whole test procedures including injecting oil, determination, removing oil and test result printing are automatical.
