Instrument Features

1. Fast measurement speed. The results are usually obtained within 3 to 5 minutes, with the fastest time being 1 minute. The entire process of injection, measurement, cleaning, drying, and result calculation generally does not exceed 10 minutes.

2. High degree of automation. Measurement, cleaning, drying, and result calculation are all automatically completed.

3. There are many types of samples for measurement. It can measure transparent and opaque samples, including Newtonian liquids such as gasoline, diesel, kerosene, cutting fluid, heat transfer oil, additives, lubricating oil, and in use oil.

4. Clean quickly and efficiently, with low cleaning costs. A cleaning process generally consumes no more than 10 milliliters of cleaning solution.

5. Multiple auxiliary functions. Includes: constant calibration, temperature calibration, internal clock timing verification, automatic calculation of viscosity index, and automatic conversion of kinematic viscosity to Engler viscosity.

6. Dual over temperature protection for software and hardware, over temperature alarm, and anti dry burn protection function.

7. Using double-layer glass cylinders for more uniform temperature.

8. Using PT100 temperature sensor, the temperature of the constant temperature bath is stable and accurate, with a temperature control accuracy of 0.1 ℃.

9. The temperature rise and fall speed is fast. The maximum heating and cooling rate is 5 ℃/minute.
