    Rotational Viscometer Applications

    Tips: How does the digital rotational viscometer measure viscosity?

    A digital rotational viscometer measures the viscosity of a fluid by measuring the torque required to rotate a spindle at a constant speed inside the fluid.

    The viscometer consists of a spindle or rotor that is suspended from an arm or shaft and immersed in the fluid whose viscosity is to be measured. The spindle is connected to a motor that rotates it at a constant speed while the arm is fixed in place. The spindle experiences resistance to its motion due to the viscosity of the fluid, which generates a torque that can be measured by a sensor.

    The torque sensor is connected to a digital display unit that measures the torque and displays it as viscosity units. The digital display unit can be programmed to display the viscosity in different units such as centipoise or millipascal seconds, depending on the user's requirements.

    The rotational speed of the spindle is also a factor in the measurement of viscosity. The viscometer typically has different speed settings which can be adjusted to ensure that the measurement is accurate for the particular fluid being tested.

    Overall, the digital rotational viscometer provides a precise and accurate method for measuring the viscosity of fluids, which is useful in a wide range of industries such as pharmaceuticals, food and beverage, and petroleum.

    Existing reviews of Digital Rotational Viscometer, 3-1600000 mPa.s
    Are there any overall cleaning advice of rotational viscometer?
    I recently purchased the  ATO-VISCO-SSR. I have been cleaning the rotor and cup between runs with isopropyl and have noticed a build-up and a slight visual discoloration on the rotor.
    Are there any specific organic solvent recommendations?
    Are there any overall cleaning recommendations?

    ATO Responded
    The rotors are all 304 stainless steel, not resistant to strong acids and alkalis.
    You can use common solvents like alcohol, or acetone.
    The rotor and cup can also be wiped with toilet paper.
    Rotary viscometer calibration procedure
    I recently purchased the LV-SSR rotary viscometer. What is the recommended calibration procedure and method for the ATO viscometers? There is no information in the manual or on your website.
    Also, the viscosity range I will most likely be using is between 100-200 CP, using the 18 rotor.

    ATO Responded
    Sorry for the late response.
    Calibration of the viscometer requires the purchase of a standard viscosity fluid and an accurate constant temperature at 25°C. Measure the viscosity of the standard viscosity liquid.
    If the error with the standard value of the standard viscosity liquid is greater than ±5%, calibration is required.
    Calibration requires two conditions:
    1. Standard viscosity liquid.
    2. A constant temperature bath that can precisely control the temperature at 25°C.
    For standard viscosity liquid, please refer to the following specifications. Standard silicone oil comes in various specifications, 450ml per bottle:
    1. 47.42mPa.S
    2. 341.1mPa.S
    3. 4749mPa.S
    4. 9853mPa.S
    The specific viscosity value shall be subject to the shipping label.
    Hope my explanation is able to assist you. Please feel free to let us know if you have any further questions.
    e measurement range of No. 18 rotor is 3-10000 (10,000) mPa.S (CP), No problem.
