Automatic Vapor Pressure Tester (Reid Method) ASTM D323

Automatic Vapor Pressure Tester

The Vapor Pressure Tester is designed and made as per the national standard of People’s Republic of China GB/T8017 “Standard Test Method for Vapor Pressure of Petroleum Products (Reid Method)” and ASTM D 323 Standard Test Method for Vapor Pressure of Petroleum Products (Reid Method). It is suitable to determine vapor pressure of gasoline, volatile crude oil and other volatile petroleum products. It cannot be used to determine the vapor pressure of LGP.

Working principle:

Fill the cooled sample into the gasoline chamber of the vapor pressure tester, connect it to air at a certain temperature, and then immerse the tester in a constant temperature bath. At the specified temperature, the gas-liquid phase reaches equilibrium, and the maximum pressure displayed by the liquid level vapor is the saturated vapor pressure. The tester automatically detects and displays this pressure value through devices such as pressure sensors.

Main technical specification and parameters:

1. The upper software of automatic vapor pressure tester is installed on PC, it can follow the user’s orders, collect the data collected by the lower computer, and it can also analyze, calculate, draw, display, save and print automatically.
2. Main control board: the internal use of SCM control, according to the procedures set in advance, under the control of the PC machine,to make coordinated operation of all parts of the system.
3. Water bath circulation system: to provide the suitable test temperature for the test chamber.
4. Temperature controller: to control the temperature of the constant water bath, make the temperature keep in the range of 37.8±0.1℃.
5. Test chamber: to meet the requirements of the national standard, easy to operate,the maximum pressure is 1Mpa.
