Low Temperature Kinematic Viscometer

Low temperature kinematic viscometer is a precision instrument specifically used to measure the kinematic viscosity of liquids in low-temperature environments. Its core function is to quantify the flow resistance of liquids at low temperatures and reflect their viscosity characteristics. It is widely used in fields such as petrochemicals, automotive industry, aerospace, and is particularly important for evaluating the low-temperature performance of fluids such as lubricants and fuels.

Structure and Principle:

1. In order to achieve the required experimental temperature test, use two refrigerant and circulatory system composed of cascade refrigeration, to meet the evaporation press at a lower evaporation temperature appropriate evaporation, as the two refrigerant condensation in the same “Evaporative condenser”to complete, and this equipment and the external environment with thermal insulation material isolation. This results in a lower evaporation temperature and refrigeration. When the temperature inside the bath is lower than the temperature set by the temperature controller, the temperature controller automatically outputs the signal and drives the heater through the solid state relay to achieve the purpose of constant temperature.
2. Low Temperature Kinematic Viscometer is mainly composed of  the refrigeration system, control system, measurement system and other components.
3. Refrigeration system: high-temperature units, low-temperature units, temperature relays, filters, cold head (input evaporator) and other components. Using the international advanced compressor cascade refrigeration technology. Low freezing point of the media as a refrigerant, with cooling speed, cooling temperature and other advantages.
4. Control system: It consists of stirrer, digital temperature controller, heater, sensor, cold bath and temperature control circuit. The bath temperature is realized by thermal balance, which has the advantages of fast response and high temperature control accuracy.
5. Measuring system: Capillary viscometer, clamp cover and other components, the clamp cover with leveling function, this device can reduce the experimental error, improve the accuracy of the experiment.
