Red Wood Viscometer apparatus are widely used in petroleum laboratories, oil refineries, industries, educational institute, research organizations and various other institutions for study of the red wood viscosity of petroleum products.Two adaption of redwood viscometer are available NO.1 for liquid having redwood flow 20 second to 2000 second and no.2 for liquid  whose flow time with no.1 exceed 2000 seconds.The complete outfit comprises stainless steel bath having drain plug with elec.
Heating arrangements able to operate at 220 volts 50 hz ac mains or gate heating arrangements, with tap, silver plated oil cup with precision stainless steel jet, ball valve ,cover thermometer clip, stirrer, and suitable stand with  leveling screws. In elec. Heating arrangements the temp. is controlled by energy regulator model / solid state elec. Regulator model / voltage varrier copper coil type model / digital temp. controller cum indicator type model.

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 temparature range upto 1000C plus minus 20C.
