　　Automatic Distillation Range TesterIt is an instrument used to determine the vapor pressure and distillation range of petroleum products, chemical products, and other liquid samples. It adopts automation technology and has the characteristics of high precision, high efficiency, and reliability.

【 Working Principle 】

　　Automatic Distillation Range TesterBased on the principle of distillation range determination, the sample is heated and separated into different components, and then detected and recorded according to the boiling temperature of each component. During the measurement process, the sample is heated from the contact heating surface and gradually converted into gaseous components based on its volatility, and then condensed and collected at different temperatures. Based on these collected components, the vapor pressure and distillation range of the sample can be determined.
