Lubricating Oil High-Temperature and High-Shear Viscometer (HTHS)

Lubricating Oil High-Temperature and  High-Shear Viscometer (HTHS)

Introduction:

The instrument mainly measures the apparent viscosity of lubricating oil at high temperature and high shear rate. The test principle is that under the test condition of 150 °C, under the pressure of nitrogen (carbon dioxide), the sample flows out from the capillary viscometer, and the apparent shear rate of the capillary viscometer can be obtained from the outflow time and pressure of the sample. To achieve a certain apparent viscosity, the curve corrected by each viscometer pool corresponds to the measured viscosity of the oil viscosity.

Technical Parameters:

1. The instrument has been widely used by the customers both in China and outside China.

2. Accessories can be exchanged with imported instruments

3. Equipped with special high shear viscosity calculation software.

4. The instrument allows 24 hours a day, 365 days uninterrupted operation;

5. No solvent cleaning is required, only a small amount of fresh sample is required for rinsing.

6. The glass capillary tube meets the standard requirements, with a diameter of 0.15mm and a lenght of 16mm.

7. For the purpose of research, users can set different shear rate and test temperature;

8. 5 sample units can be continuously and quickly measured one by one, 15 ~ 20 samples can be measured per hour.

9. Touch LCD control, can be operated directly on the LCD screen;

10. The software automatically recommends the test pressure, and the test results can be generated by Excel report;

11. We’re patented for the oil shear viscometer patent, the patent No. is ZL201821712254.6

Reference Standards:

1. SH/T-0703 Standard test method for measuring apparent viscosity at high-temperature and high-shear rate by multicell capillary viscometer.

2. ASTM D5481 Standard Test Method for Measuring Apparent Viscosity at High-Temperature and High-Shear Rate by Multicell Capillary Viscometer.
