SH417 High Temperature High Shear Tester ASTM D5481 7mL Sample

SH417 High Temperature and High Shear Tester

The SH417 high-temperature and high shear tester is a petroleum product testing instrument manufactured in strict accordance with the technical requirements of the standard test method for measuring apparent viscosity at high temperatures and high shear rates using a multi capillary viscometer according to ASTM D5481. It is suitable for determining the apparent viscosity of lubricating oil at high temperature and high shear rate, that is, measuring the high-temperature and high shear dynamic viscosity of lubricating oil, HTHS index. It is also applicable to determine the dynamic viscosity and high-temperature high shear characteristics of lubricating oil under high temperature and high shear rate conditions using the SHT 0703-2001 method for measuring the apparent viscosity of lubricating oil under high temperature and high shear rate conditions (multiple capillary viscometer method).

The testing principle is to flow the sample out of the capillary viscometer under the pressure of nitrogen (carbon dioxide) under the test conditions of 150 ℃± 0.1 ℃. The apparent shear rate of the capillary viscometer can be determined by the flow time and pressure of the sample, and the viscosity of the oil corresponding to the measured pressure can be obtained by calibrating the curve of each viscometer cell.

The instrument combines the advantages of various domestic and foreign products, and has made a series of improvements in appearance design and operating program functionality, making the instrument more satisfactory to users

All accessories of the instrument are made of imported original components and processing technology, and can be exchanged with imported instruments

The dedicated high shear viscosity microcomputer software makes the testing process of the instrument simpler, more accurate, and convenient

The instrument measurement units are calibrated using American Keneng standard oil, and the experimental data is accurate and reliable

The instrument is equipped with a dedicated pressure reducing valve, making it convenient for users to connect gas cylinders and operate them.

The glass capillary tube can be completely interchangeable with imports, fully meeting the requirements of ASTM and SH/T standards, with a diameter of 0.15mm and a length of 15-18mm

The experimental data is stored by a computer and can be automatically printed.

Made of all aluminum material, neat and beautiful, with a compact size

The large touch LCD screen can intuitively display all parameters, temperature, flow changes, and other information of the experiment
