This Viscometer bath is used to maintain the correct constant temperature for estimating Kinematic Viscosity of Oil and Petroleum Products in this type of bath various viscometers may be fixed as an internal part of the bath.The bath is rectangular shape.Inside tank is made of Stainless Steel Sheet. Two sides toughed glass window provided for full visibility of objects inside the bath. The bath is controlled by an electronic relay and contact Thermometer Or Digital Temperature controller cum indicator.Temperature range 5 0 C above room temperature to 100 0 C. Accuracy plus minus 0.1 0 C. Stirring is done by a FHP electric motor stirrer.Heating is done by means of tubuler type heater fitted on top of the bath.It is supplied with viscometer tube holders and stainless steel cover. Different size & accomodation are available as under without Viscometer tube. Note : 1. Please mention correct size and viscosity range of viscometer tubes with indent/order. 2. 'U' Tube with constant test certificate at an extra cost for each tube. 3. A circulating pump instead of stirrer can be provided on the extra cost.  4. Powder coating instead of enamal paint can be also be provided at extra cost.

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.

Used for determining the Viscosity of fuel oil and lubricating oil both thin & thick. The apparatus consists of Stainless Steel bath with oil cup which is centrally placed in a water bath. The bath has a lid which contains a water cooling tube, two handle with two stirrer blades, thermometer socket and a straight heater, stirring is done by turntable arrangement. A thermometer can also be inserted into the cup cover. The jets one universal and one Furol can be screwed to the cup by a handle(without strainer, withdrawal tube and glasswares). can operate on 220 Volts AC mains

Used for determining of the closed cup Flash point of Petroleum Products, their mixtures, others liquids & Paints having Flash Point below 70 0 C. 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 is widely used for determination of closed cup Flash Point of Fuel Oil, cut back asphalts, other viscous material and suspension of solids having a flash point about 49 0 C(120 0 F).The apparatus serve the purpose according to IP 34, ASTM-D-93-58T, IS-1448(P:I) 1960(P:21) and IS 1209/1958 method B. The apparatus consists of Brass Test cup with handle removable cup cover with spring operated rotating shutter having piolet jet, stirrer with flexible shaft. The assembly rests in Air Bath which is covered with Dome shape metal top. The cup is fitted with insulated handle and locking arrangement near cup plange. The assembly rests on a round shaped heater with different temperature regulation system suitable for operation on 220 Volts AC mains.

This is made as a specified by IP-15, ASTM-D-97/57 & IS-1448-1970 the pour point is the lowest tempertaure at which the oil will just fail to flow. The apparatus consists of a main cooling bath made of stainless steel sheet and stand unit with drain plug and cover with provision for fitting thermometer and a filling aperture for adding freezing mixture. A glass jar for containing oils, jacket, disc and gasket as specifed are also provided.
