Summary
GD-510Z-1 Automatic Solidifying Point&Pour Point Tester is made as per standards GB/T 510 Standard Test Method for Solidifying Point of Petroleum Products,GB/T3535 Standard Test Method for Pour Point of Petroleum Products. It is a kind of high automatic instrument with advanced design. It is used to determine the solidifying point and pour point of light oils which have good flow ability and low viscosity such as gasoline, light diesel oil and transformer oil. It can be widely used in oil refineries, oil stations and other relevant institutions.

I. Main technical features

1. It adopts SCM as the core control system. Colored touch screen. It can track and display the real-time temperature, and simulate the test status intelligently.
2. It adopts high accuracy detecting sensor and semiconductor refrigeration technology. The test precision is high.
3. It uses little mass of oil sample. The test is rapid(5~10 min for one test). The test procedures are completed automatically are injecting the sample. It has good stability and repeatability. The result is reasonable. The test result can be printed after test.
4. The instrument needs less sample for the determination. The intelligence is high. It can do the test automatically after the sample is added. A micro-printer is equipped.
