The HT-900Z fully automatic freezing point and pour point tester complies with the provisions of the national standards GB510 “Method for Determining the Freezing Point of Petroleum Products” and GB3535 “Method for Determining the Pour Point of Petroleum Products”. It is used to determine the freezing point and pour point of transformer oil, lubricating oil and light oil (not suitable for petroleum products with high viscosity). It adopts a color touch LCD screen display, a Chinese human-machine dialogue interface, is convenient and intuitive to operate, and has a software prompt modification function for misoperation. The interface is clear, and it can print test data. It realizes the automation of the test process and is an ideal product for measuring freezing point and pour point.

Instrument Features：

1. Color Chinese and English touch screen operation, micro single-chip microcomputer intelligent temperature control, fully automatic detection of sample freezing point and pour point;

2. Graphical dynamic simulation of working conditions is adopted, and the test process is reproduced on the screen.

3. It can track the changes in oil temperature in real time, with a testing accuracy of ±0.1℃. It can be heated to 25℃ or cooled to -70℃.

4. The entire process is automatically detected, with accurate test results, good repeatability, stability and reliability, simple operation, and the ability to print experimental results.

5. During detection, the tilting frame automatically tilts at 45 degrees for detection. The testing mode is selectable, allowing for either rapid detection or normal detection.

6. High-performance compressor refrigeration, fast cooling speed and long service life;

7. The fault diagnosis function automatically prompts to prevent measurement errors.

8. It has a powerful storage capacity, capable of storing 300 records and can be expanded to 500G storage (optional) to achieve unlimited storage and access historical records at any time；
