![]() The 20x Duplo viscosity tube is suitable for uneven samples with poor repeatability and uncertainty during repeated sampling. Clower is for high viscosity sample detection, and Cupper is for low viscosity sample detection. The 100 times viscosity tube is suitable for homogenous samples and has two different detections areas, namely Clower and Cupper, are present. The instrument offers two sensor options for the homogenous nature of the sample, one is 100 times the normal viscosity tube, and the other is 20 times the Duplo viscosity tube. Optical sensor viscosity tube: suitable for transparent and conductive fluids such as polymer samples.Thermal sensor viscosity tube: suitable for opaque and transparent non-conductive samples, such as lubricating oil samples.Simply change the viscosity tube per the sample. One major thing about an automatic viscometer is that it provides the user with various viscosity tubes which can be selected based on the requirement. The device should be chosen based on sample nature and offers a suitable viscosity tube.How to choose a fully automatic kinematic viscometer?Īs kinematic viscosity is an essential technical property for oil and equipment lubrication management, what needs to be considered before choosing a fully automatic kinematic viscometer? Therefore, kinematic viscosity is a critical factor in lubricant categorization. Varying grades of lubricating oils have different kinematic viscosities. Refined oil is prepared by bleeding and stirring base oil and additives in lubricating oil. A direct relationship exists between dynamic viscosity and low-temperature fluidity, but kinematic viscosity shares an inverse association with lubricating oil viscosity.Ī kinematic viscometer is widely used in viscosity measurement experiments. Both viscosity types are considered indicators that assess lubricating oil viscosity. The unit is pa.s and is calculated by μ=τ/(du/dy). The force required to produce a unit flow rate using a unit area of a liquid layer per unit distance is termed Dynamic viscosity. The unit is (m²)/s and is calculated by ν=μ/ρ The fluid’s dynamic viscosity ratio to the fluid’s density at the same temperature is termed Kinematic viscosity. It represents the amount of electrical resistance existing between molecules. Viscosity is defined as the internal friction of a liquid. The two main methods of measuring viscosity are dynamic viscosity and kinematic viscosity. On the contrary, low viscosity fluids flow relatively quickly and have fewer stress deformation chances. High viscosity fluids are more prone to deformation by stress and show resistance in flow. Viscosity is one of the most critical factors that directly influence the flow properties of a liquid. ![]()
