Description

Technical Field

[0001] The utility model relates to the technical field of fuel oil flash point detection, in particular to a fuel oil flash point detector. Background Art

[0002] Flash point is a safety indicator for the storage, transportation and use of flammable liquids. It is also an indicator of the volatility of flammable liquids. Under specified test conditions, the lowest temperature at which a liquid can be vaporized and ignited using a certain ignition source. Flash fire is when enough vapor is generated on the surface of a liquid and mixed with air to form a flammable gas. When it encounters a fire source, a short flame is generated, which flashes and then goes out. This phenomenon is called flash fire, and the lowest temperature at which flash fire occurs is called flash point. During use, the existing fuel oil flash point detector needs to heat the fuel oil first, and the fuel oil is generally placed in a test cup, which causes uneven heating of the fuel oil inside the test cup, affecting the accuracy of the test results. Therefore, we have launched a new fuel oil flash point detector. Utility Model Content
