Oil And Petroleum Testing Instruments

Product Details:

Redwood viscometer apparatus are widely used in Petroleum Laboratories, Industries, Oil Refineries, Educational Institutions,Research Organisations for standerdisation and determines the Viscosity of Petroleum products, which flows in a newtonian liquid except cut back Bitumens and road oils at the set temperature, They confirm to requirement of IP 70. Two adaption of Redwood Viscometers are available.Redwood Viscometers No. I for liquids having Redwood Flow 20 seconds to 2000 Seconds and Redwood Viscometers No. II exceeds 2000.The complete outfit comprises hemmertone finish, copper/Stainless steel bath with drain plug, electrical heating arrangement,Suitable to operate at 220 Volts 50 Hz AC mains Or gas heating arrangement with silver plated oil cup with precision stainless steel jet, ball value, cover, thermometer clip,stirrer and suitable stand with levelling screws. The sample required to be tested, is to fill in to the required level as indicated by the gauge in a cup having a Stainless Steel jet fixed in the bottom. The temperature is maintained during the test by heating the liquid in a bath surrounding the cup,and the flow time for 50 ml of the sample is measured.

Product Details:

Used for determining of the closed cup Flash point of Petroleum Products,their mixtures, others liquids & Paints having Flash Point below 700C. The apparatus consists of one brass cupand cover fitted with shutter mechanism test flame arrangement(Oil test jet or Gas test jet) and stirrer, placed on a water bath made of Stainless Steel double walled. The outer jecket of the water bath is fitted with a stand. For electrically heated apparatus,heater is fitted to the stand the heat of which may be controlled different temperature regulation system of operated on 220 Volts AC mains. For Gas heated model the drum is heated by a burner.(without burner).

This apparatus is meant for determination of softening point of Bituminious materials according to IP 58 and IS 1205-1958. Softening point is that temprature at which the speciman under test becomes soft enough to allow a steel ball of specific dimension to fall a required distance under test condition . The apparatus consists of glass beaker,ring stand two steel balls with ring and ball guides & hand stirrer.

ASI-412     Softening Point Apparatus(without glass beaker)
ASI-412C   Softening Point Apparatus(with glass beaker)
ASI-412/A  Softening Point Apparatus (Ring & Ball Apparatus),with electric motorised stirrer and electric heater ,stand with temperature regulator.
ASI 412/B  Softening pointapparatus with motorised stirrer , electric heated by concealed hot plate with temperature regulator.

Optional Accessories:

1. ASI -412/A    Thermometer IP 60C.
2. ASI -412/B    Thermpmeter IP61C.
3. ASI -412/C    Spare Concealed Hot Plate.
4. ASI -412/D    Spare centring guide and steel ball(Pack of 2 Nos).

This apparatus is used for penetration test on a wide variety of materials such as grease, Petroleum, Bitumen, Tar, Wax, Polish, food stuff, Rubber asphalts and pharmaceuticals Creams.A given force is applied over a given of a millimeter and expressed as penetration.It consists of a head support mounted on a vertical rod which can be adjusted for height. A rack and pinion and pointer assembly provides fine adjustment of a needle tip to sample and incorporates a slipping clutch mechanism which make reading of Penetration and subsequent resetting of a sample and accurate operation. The dial is graduated from 0-400 in on tenth millimeter Sub Division. The instrument is supplied with two samples containers made of aluminium. The penetration is the distance in millimeter that a standard needle penetrates vertically into a sample of the material under fixed conditions of loading time and temperature. This instrument measures the reading on round dial fitted on a Aluminium Painted stand having adjustable penetration needle, holder sample container and transfer dish.

Optional Accessories:

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.

Optional Accessories for V.P. Bomb for L.P.G. :

1. 20% Ullage Chamber
2. 33% Ullage Chamber
3. Air Chamber
4. Pressure guage any range

Note : Digital temprature Controller Cum indicator can be supplied at an extra cost.

Optional Accessories :

1. ASI-576/A Gauge for above any of the range 0-15 psi or 0-45 psi or 0-60 psi or 0-100 psi each range.
2. ASI-576/B     Spare Air Chamber.
3. ASI-576/C     Spare Gasoline chamber without cock.
4. ASI-576/D     Spare Gasoline chamber with cock.
