The fully automatic micro saturation vapor pressure tester is a modern analytical instrument used to accurately determine the saturation vapor pressure of volatile liquid petroleum products. The fully automatic micro saturation tester is mainly used to measure the saturation vapor pressure of liquids (such as gasoline, solvents, etc.), and has the characteristics of fully automatic operation, low sample consumption, fast testing, and accurate results. It is suitable for various application scenarios in laboratories and fields.
Based on the principle of thermodynamic equilibrium, the sample temperature is accurately adjusted through a built-in temperature control system, causing liquid molecules to evaporate and form vapor in a closed space, reaching dynamic equilibrium with the air above. At this point, the pressure inside the container is the saturated vapor pressure. The instrument uses high-precision pressure sensors to monitor in real time and automatically calculate the output results.
Fully automatic operation: The instrument integrates an automated testing program, which eliminates manual intervention from sample injection to result output, eliminating operational deviations.
Equipped with a wide color touch screen or embedded computer, supporting Chinese interface operation, providing intuitive guidance for users to complete the test.
Easy to operate: Equipped with a digital display screen or touch screen, it guides the operation and displays the test results. All valves operate automatically without excessive manual intervention.
Small sample size: Generally only 3ml of sample is needed, reducing sample consumption, especially suitable for testing precious samples.
High measurement accuracy: The temperature control accuracy can reach ± 0.1 ℃, and the pressure sensor resolution is high, with some instruments reaching up to 0.01kPa, ensuring accurate and reliable measurement results.
Versatile features: It can automatically calibrate temperature and air pressure, provide multiple test result unit options, some instruments also have data recording, analysis, and reporting functions, and support connection to external devices such as printers and LIMS systems.
Application field
Petrochemical industry: Determine the saturated vapor pressure of light distillate oils such as gasoline, aviation kerosene, and turbine fuels, evaluate volatility and safety. Monitor the vapor pressure of crude oil, hydrocarbon solvents, and chemicals to guide production and storage.
Environmental monitoring: Analyze the vapor pressure of volatile organic compounds in natural water sources and soil to assess environmental pollution risks.
Research and Education: Used for vapor pressure research in fields such as materials science and chemical engineering, supporting teaching experiments.
