Reid Vapour Pressure

Technical Description
 

Used to determine the vapour pressure of volatile non-viscous Petroleum products except liquified petroleum gases.

The Vapour pressure is made up of brass heavily Chronium plated and consists of an air chamber and a gasoline chamber of definite dimensions and volume ratio. A pressure gauge of required range is fitted above the air chamber. The joints are made leak proof by neoprene washers. The water bath used is of such dimensions that the vapour pressure bombs may be immersed to at least 1 inch above the air chamber and maintained at a constant temperature range upto 100⁰C plus minus 2⁰C.
