Introduction to SDW-552 Automatic Tube Folding Kinematic Viscometer

SDW-552 Automatic Tube Folding Kinematic ViscometerIt is an automated instrument for quickly measuring the kinematic viscosity of oil products, according to standards: ASTM D7279 、D445、D446、NB/SH/T0956-2017、T/CEC127-2016， The measurement results meet and exceed the requirements of the GB/T265 standard for design and manufacturing; This instrument has a fully automatic cleaning function and its performance is comparable to similar imported instruments.

Functional features:

1. Fast measurement speed. The fastest time to get results is 1 minute, and generally it takes 3-5 minutes to get results. 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. The temperature rise and fall speed is fast. The fastest temperature rise and fall rate is 5 ℃/minute.

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

9. Using PT500 high-precision temperature sensor, the temperature of the constant temperature bath is stable and accurate, with a temperature control accuracy of 0.01 ℃.

10. Can be equipped with disposable filters, greatly reducing the workload of experimental personnel in sample pretreatment.
