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 wax oil, lubricating oils and other petroleum products with high boiling point range. It adopts IPC control technology to control the vacuum pressure automatically. It adopts high accuracy temperature sensor to detect the steam temperature automatically. No need to observe it by naked eye. It adopts LCD technology, can input, modify and show parameters and control them by touch screen. Except that the distillate volume is read manually, all other work is completed automatically by the instrument.
