Features
- 01.The kinematic viscosity tester adopts a digital temperature control meter to control the temperature of the constant temperature bath, and the temperature control range is -70～50℃, Temperature control accuracy ±0.1℃
- 02.The test panel is equipped with two test holes and two viscosity tube brackets, which can keep other samples to be tested constant temperature at the same time when the sample is measured, so as to improve work efficiency
- 03.The test panel is equipped with horizontal bubbles, and the bottom feet of the instrument can be adjusted according to the needs, which is suitable for different test tables
- 04.The cascade compressor refrigeration mode is adopted to realize high-performance and low-temperature refrigeration
- 05.The bathtub adopts dewar bottles to effectively keeps warm and prevents frost formation
working principle
Working principle of theKinematic Viscosity Tester TP6251
- The sample was loaded into a capillary viscometer and the water bath was heated to a set temperature and kept constant. Place a suitable capillary viscometer in a temperature-adjusted thermostatic bath and let it stand still. Measuring the time for a certain volume of liquid to flow through a glass capillary viscometer under gravity. The product of the capillary constant of the viscometer and the flow time is the kinematic viscosity of the liquid measured at this temperature. The product of the kinematic viscosity at this temperature and the density of the liquid at the same temperature is the dynamic viscosity at this temperature.

Precautions
1. Avoid violent vibration when using or transporting the automatic kinematic viscosity tester.
2. Before using the automatic kinematic viscosity tester, first connect all the connecting wires completely.
3. If any abnormality is found during the use of the kinematic viscosity tester, the power supply should be cut off immediately.
4. Before controlling the temperature, make sure that the oil bath in the oil bath box is kept near the scale line.
5. When doing experiments with high temperatures, be careful not to touch the oil bath or observation window directly with your hands to prevent burns.
