NR7620 series closed flash point automatic tester
Closed flash point automatic tester, when the test sample is used in a closed environment (such as transformer oil), the closed flash point value of petroleum products is determined. Use touch screen instead of keyboard operation, adopt foreign advanced technology, large LCD screen LCD full Chinese display man-machine dialogue interface, full screen touch button prompt input, convenient and quick, open, fuzzy control integrated software, modular structure, in line with national standards, the United States, European Union and other standards. It is an ideal substitute for imported instruments. It is widely used in railway, aviation, electric power, petroleum industry and scientific research departments.
