Our CE-marked Reid Vapour Pressure Apparatus is a precision instrument for measuring the vapour pressure of gasoline, volatile crude oils, and other petroleum products. Compliant with ASTM D323, IP 69, and ISO 3007, this apparatus is ideal for laboratories and fuel testing facilities requiring accurate determination of vapour pressure for regulatory and quality control purposes.
Product Overview
The Reid method determines vapour pressure for fuels under controlled conditions:
• Procedure A: Gasoline and petroleum products with vapour pressure <180 kPa (26 psi). • Procedure B: Similar materials; precision verified with gasoline only. • Procedure C: Petroleum materials with vapour pressure >180 kPa (26 psi).
• Procedure D: Aviation gasoline with vapour pressure ~50 kPa (7 psi).
Not suitable for liquefied petroleum gases or fuels with oxygenated compounds other than MTBE.
