I. Summary
The instrument is used to determine closed cup flash point of petroleum products. The instrument adopts colored LCD screen, man machine conversation interface, blank buttons, open and fuzzy controlled integration software, and modular structure. It can preset temperature, sample ID, barometric pressure, test date, and other parameters. It has prompt menu and input guide. The instrument is automatic, convenient, and rapid. It can meet the requirements of the National Standard of People’s Republic of China GB/T261-2008 “Test Methods for Flash Point of Petroleum Products （Pensky-Martens Closed Cup Method）”. It is the best choice of similar products. It can be widely used in the field of railway, aviation, power plant, petroleum industry, and scientific research institutes.
II. Purpose and scope
The instrument is designed and made as per the National Standard GB/T261-2008 “Test Methods for Flash Point of Petroleum Products （Pensky-Martens Closed Cup Method）”. It is suitable to determine closed cup flash point of petroleum products, which is expressed as the lowest temperature when the mixture of its vapor and air contacts flame and appears flash, using a closed oil cup under the stipulated condition.
