The kinematic viscosity tester under the UHV power company can help many power workers conduct various power tests more conveniently.

Kinematic viscosity is an important indicator of lubricating oil. What we need to do when purchasing is to use an automatic kinematic viscosity tester to measure the kinematic viscosity of lubricating oil. After multiple measurements, there is often a certain degree of error in the results., What are the factors that affect the measurement results of this instrument? Below is a detailed analysis of this issue for everyone, let's take a look together!

1. Constant temperature and temperature control directly affect the results of viscosity measurement. When the temperature rises, the measurement results of the automatic motion viscosity tester are lower; The temperature decreases, resulting in higher viscosity measurement results. Therefore, it is necessary to carefully control the testing temperature to ensure that its temperature variation is within the tolerance requirement (± 0.1 ℃).

2. Determine different lubricating oils, choose a suitable viscosity tester, and ensure that the lubricating oil flows in the capillary tube of the viscosity meter for no less than 200 seconds. When the flow time is less than 200 seconds, due to the fast flow velocity, the lubricating oil will flow in a turbulent state inside the capillary tube, resulting in larger test results.

3. The verticality of the installation of the automatic motion viscosity measuring instrument is another important factor that affects the measurement results. When the capillary is tilted, the measurement result will increase or decrease.

The measurement results of the automatic motion viscosity tester are mainly affected by the above factors. Therefore, we need to pay attention to these aspects when using instruments for measurement. At the same time, keep the oil clean and free of water to reduce size and measurement errors.
