GD-H1706 ASTM D5481 High-Temperature High-Shear Dynamic Viscosity Tester (HTHS)

Suitable for engine oils, the calibration curve is established with Newtonian calibration oils with apparent viscosities ranging from 1.5 mPa·s to 5.0 mPa·s at 150°C, and the apparent viscosity is directly measured. This precision is only applicable to engine oils with apparent viscosities between 1.45 mPa·s and 5.05 mPa·s at 150°C.

GD-H1706  ASTM D5481 High-Temperature High-Shear Dynamic Viscosity Tester (HTHS)

High Temperature High Shear Dynamic Viscosity Tester1

This ASTM D5481 instrument measures the high-temperature high-shear (HTHS) apparent viscosity of engine oil under conditions of 150°C and an apparent shear rate of 1.4×10^6 s^-1 on the wall of the tube, using a multi-channel capillary viscometer equipped with pressure measurement, temperature measurement, and timing devices.


Main Features:

◆ This instrument is widely used by most domestic customers;

◆ Accessories are interchangeable with imported instruments;

◆ Equipped with dedicated high-shear viscosity calculation software;

◆ The instrument allows for continuous operation 24 hours a day, 365 days a year;

◆ No need for solvent cleaning, only a small amount of new samples are required for flushing;

◆ The glass capillary tubes meet standard requirements, with a diameter of 0.15mm and a length of 16mm;

◆ For users with research purposes, different shear rates and test temperatures can be set;

◆ Manufactured using all-aluminum materials;

◆ Touch liquid crystal screen control, allowing direct operation on the LCD screen;

◆ The software automatically recommends test pressure, and test results can be generated in Excel report format;

◆ Patent for oil shear viscosity meter, Patent No.: ZL201821712254.6.
