Product Features
High-temperature viscometer has the characteristics of high measurement sensitivity, reliable test results, easy operation, and elegant appearance. It is a precision instrument used to measure the absolute viscosity of Newtonian liquids and the apparent relative viscosity of non-Newtonian liquids. It can be widely used in products such as oils, paints, plastics, medicines, foods, coatings, adhesives, viscometers, resins, and chemical raw materials.
High-temperature viscometer is a high-temperature digital viscometer. The motor drives the rotor to rotate at a constant speed through a variable speed belt. When the rotor rotates in the liquid, the liquid will produce a viscosity torque acting on the rotor. The greater the viscosity of the liquid, the greater the viscous torque; conversely, the smaller the viscosity of the liquid, the smaller the viscous torque. The viscous torque acting on the rotor is detected by a sensor, and the viscosity of the tested liquid is calculated after being processed by a computer.
It is equipped with 4 types of rotors (R21, R27, R28, R29) and two variable speed modes: infinitely variable speed and fixed speed. The fixed speed mode has 10 speed levels (0.5, 1, 2, 2.5, 4, 5, 10, 20, 50, 100 rpm), which form 40 combinations that can measure the viscosity values of various liquids within the measurement range. It is also equipped with a temperature measurement device, which can directly display the temperature on the screen, allowing the observation of the viscosity change caused by temperature variation.
