Petroleum testing is the analysis during upstream, midstream, and downstream production processes of petroleum products. It is most commonly used to test petroleum product, its product components, byproducts of crude oil, fuel, natural gas, upstream oil and gas and other formats of petroleum. - The instrument is suitable to determine the distillation characteristics of gasoline, aviation gasoline, jet fuels, special boiling point solvent, naphtha, diesel oil, distillate and similar petroleum products. The instrument adopts aquartz heating furnace form to ensure the safety of the test, and the heating power is continuously adjustable. The height of the flask is adjusted by the lifting device, and the observation window of high-temperature and heat-insulating glass is equipped to observe the whole test process. The instrument is equipped with a cylinder receiving chamber, which can measure the distillation range of gasoline.
