Many users overlook this point and believe that a slight temperature difference doesn't matter. Our experiments have shown that when the temperature deviation is 0.5 ℃, the viscosity value of some liquids deviates by more than 5%, and the temperature deviation has a significant impact on viscosity. As the temperature increases, the viscosity decreases. So special attention should be paid to keeping the temperature of the measured liquid constant near the specified temperature point, and not exceeding 0.1 ℃ for accurate measurements.
