This instrument is suitable for determining the kinematic viscosity and dynamic viscosity of liquid petroleum products (referring to Newtonian liquids). This method involves measuring the time it takes for a certain volume of liquid to flow through a calibrated glass capillary viscometer under gravity at a constant temperature. The product of the capillary constant of the viscometer and the flow time is the kinematic viscosity of the measured liquid at that temperature.

    It is applicable to standards such as “GB265-88 Determination of Kinematic Viscosity of Petroleum Products” and ASTM D445. It adopts a precision digital temperature controller to control temperature, with digital temperature display, high temperature control accuracy, digital stopwatch for timing, and uniform temperature in the thermostatic bath. It can accommodate four viscometers for experiments simultaneously and can also be used as a high-viscosity thermostatic water bath for other experiments.

Main Features:

 1. A precision digital temperature controller is used to control the temperature inside the bathtub, and a high-brightness digital stopwatch is used for timing, which is accurate and easy to use.

 2. 10-liter constant temperature bathtub, with an outer layer of plexiglass insulation cover, uniform temperature distribution in the bath, and good temperature control effect

 3. Components such as the heater are made of stainless steel, which is corrosion-resistant and durable. It is illuminated by a circular fluorescent lamp, making observation easy.

 4. Four viscometer mounting holes allow parallel testing of more than two oil samples simultaneously.

 5. The capillary meter card adopts a three-point vertical type, which is flexible and convenient to operate, and has reliable clamping.
