ASTM D5481 Apparent Viscosity at High-Temperature and High-Shear Rate Tester High Temperature High Shear petroleum lubricant

Product Description

Apparent Viscosity at High-Temperature and High-Shear Rate Tester
ASTM D***1
Product model: JF***3Z
Product Introduction
The instrument mainly measures the apparent viscosity of lubricating oil at high temperature and high shear rate. The test principle is to make the sample flow out of the capillary viscometer under the pressure of nitrogen (carbon dioxide) under the test condition of **0℃. The outflow time and pressure of the capillary viscometer can be obtained, and the apparent shear rate of the capillary viscometer can reach a certain apparent viscosity. The curve calibrated by each viscometer cell and the oil viscosity corresponding to the measured pressure can be obtained.
