Ubbelohde viscometer with water bath

1Ubbelohde viscometer with water bathPurpose and Scope of Application

The manufacturing of this instrument complies with the requirements specified in the industry standard SY/T5561 "Technical Conditions for Petroleum Product Kinematic Viscosity Testers" of the People's Republic of China. This instrument is suitable for measuring the kinematic viscosity of liquid petroleum products (referring to Newtonian liquids) under a constant temperature condition in accordance with the provisions of the Chinese standard GB/T265 "Determination of Kinematic Viscosity of Petroleum Products and Algorithm for Dynamic Viscometers".

IIUbbelohde viscometer with water bathWorking conditions used

1. The instrument should be placed on a flat and stable experimental platform.

2. The liquid measured by this instrument is a Newtonian liquid, and its viscosity is independent of shear stress and shear rate.

3. Within different testing temperature ranges, different constant temperature bath liquids should be used for the constant temperature bath.

4. When testing the sample, an appropriate capillary viscometer should be selected according to the experimental temperature. It is necessary to ensure that the flow time of the sample in the capillary is not less than 200 seconds, and the flow time in the capillary viscometer with an inner diameter of 0.4mm is not less than 350 seconds.

Installation of instruments

1. Open the packaging box, count the spare parts, and be careful to handle glassware, especially capillary viscometers, with care. Do not forcefully pull or plug them with your hands to avoid damage.

• Fasten the plumb ball on the hook of the rubberwood cover, adjust the bottom corner screw of the chassis to make the cylinder wall parallel to the vertical line.

• Insert the thermometer and sensor into the corresponding holes on the bathtub cover.

• Connect the heater socket at the back of the chassis to the 8-pin plug of the cylinder head, and connect the three pin plug of the sensor to the three pin socket of the chassis. Connect the three core power cord plug to the three core power socket.
