The ERAVAP LPG is the ultimate solution for the automated vapor pressure measurement of LPG according to ASTM D6987. For LPG vapor pressure testing eralytics increased the standard operating range of the ERAVAP to up to 2000 kPa. ERAVAP LPG covers the model series’ temperature range of -20 °C to 120 °C and is fully compliant with ASTM D6897. As extended model it covers fuels, solvents and aqueous solutions as included in the latest international standards. ERAVAP measures the vapor pressure of crude oil following the versatile ASTM D6377 standard.
