ERAVAP Vapor Pressure Tester

ASTM D5188, ASTM D5191, ASTM D6377, ASTM D6378, ASTM D6897, EN 13016-1, EN 13016-2, EN 13016-3

ERAVAP is the ultimate solution for fully automated vapor pressure testing of automotive and aviation gasoline, hydrocarbon solvents, fragrances, polymers, crude oil and LPG as well as the vapor/liquid ratio measurement of gasoline. Powerful Peltier elements make ERAVAP the only vapor tester on the market that covers a temperature range from -20 °C to 120 °C (4 °F to 248 °F). The built-in piston draws in the sample at the beginning of the measurement. The piston then creates a vacuum by expanding the headspace above the sample to the predefined vapor to liquid (V/L) ratio. The instrument then heats up the measurement cell to the measurement temperature and records the vapor pressure.
