Reid Vapor Pressure Bath measures petroleum vapor pressure per ASTM D323, with temperature control from ambient to 100 °C and ±0.1 °C accuracy via a Pt100 sensor at 37.8 °C (100 °F). Suitable for gasoline, crude oil, solvents, and LPG, it includes a vapor pressure bomb, switch valve, and 1 MPa pressure gauge, with ASTM D1267 support. Manufactured under strict quality controls, its stainless steel, double-wall insulated construction ensures durability and thermal stability for refineries, petrochemical labs, and fuel inspection facilities."
