Viscometer Tester,Lab Viscometer,RVT-40M

Product Introduction | Features

• Rotational viscometer is an upgraded product of our company's digital viscometer. This instrument adopts more advanced mechanical design technology, manufacturing process, and microcomputer control technology.
• The data acquisition is correct and the display uses a high-resolution TFT display screen, which shows the data clearly and has more comprehensive functions.
• This precision instrument has the characteristics of high measurement sensitivity, reliable test results, easy operation, and an elegant appearance. It is designed for measuring the absolute viscosity of Newtonian fluids and the apparent relative viscosity of non-Newtonian fluids.
• It can be widely used in the measurement of products such as oils, paints, plastics, pharmaceuticals, food, coatings, adhesives, glue meters, resins, and chemical raw materials.

RVT+HBT Series:

• Viscometer Tester has the characteristics of high measurement sensitivity, reliable test results, easy operation, and beautiful 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 the measurement of various products such as grease, paint, plastic, medicine, food, coatings, adhesives, viscometers, resins, and chemical raw materials.
• Viscometer is a Viscometer Tester. 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 generates a viscosity torque on the rotor. The greater the viscosity of the liquid, the greater the viscosity torque; conversely, the smaller the viscosity of the liquid, the smaller the viscosity torque. The viscosity torque acting on the rotor is detected by a sensor, and the viscosity of the measured liquid is obtained after being processed by a computer. It comes with 6 rotors (R2, R3, R4, R5, R6, R7) and two variable speed modes: infinitely variable speed and fixed speed. The fixed speed has 10 speed levels (0.5, 1, 2, 2.5, 4, 5, 10, 20, 50, 100 rpm), which form 60 combinations that can measure the viscosity values of various liquids within the measurement range. It also comes with a temperature measurement device, which directly displays the temperature on the screen and allows the user to observe the viscosity changes caused by temperature changes.
• Shear force and shear rate can only be displayed when the 0# rotor and small sample adapter are selected.

Product Application

• LVT Series: Suitable for low viscosity materials, can measure the thinnest materials. Typical examples include: ink, oil, and solvents.
• RVT Series: Suitable for medium viscosity materials with viscosity higher than those measured by LV torque. Typical examples include: cheese, food, and paint.
• HAT Series: Suitable for higher viscosity materials with viscosity higher than those measured by RV torque. Typical examples include: gelling agents, chocolate, and epoxy resins. (Not currently available)
• HBT Series: Suitable for even higher viscosity materials with viscosity higher than those measured by HA torque. Typical examples include: asphalt, joint compounds, and molasses.
