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

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

Product Model: JF0703I

Product Introduction

The instrument mainly measures the apparent viscosity of lubricating oil at high temperature and high shear rate. According to the outflow time and pressure of the capillary viscometer, the apparent shear rate of the capillary viscometer can reach a certain apparent viscosity, and the oil viscosity corresponding to the measured pressure and the curve corrected by each viscometer pool can be obtained.
