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.

IV. Working principle
Fill sample in the test cup, and heat the test cup containing sample on the instrument as per the requirements of the National Standard GB/T261-2008. The flash point is expressed as the lowest temperature when the mixture of sample vapor and air contacts flame and appears flash.
The controlling system can send orders through I/O port as per the collected temperature changes to control the heater, so that the sample temperature will increase at a certain rate. The

flame application interval, flame application time, and flash detection can be automatically controlled. When a flash is detected, the controlling system will stop collecting data. Then the instrument will show flash point value and print out test results. The heater will stop working, the flame is extinguished, and the test arm is automatically raised up. The test is over.
