Laray Viscometer

The Laray viscometer determines the viscosity and yield value of a wide range of viscous materials.

Overview

In principle, it measures the relative velocity of two parallel surfaces, separated by a thin film of the measured visous material when a certain force (weigth of rod) is applied on one of the surfaces. The movement is hindered by the viscosity of the measured material and the travel time of the surface over a certain distance is measured.

Feature

  • rugged design
  • simple and fast method of test and easy to operate
  • automatic measurement of the time for the rod to fall between two test point
  • microprocessor based electronics for high reliablity and accuracy
  • RS232 connection to Pc for data transfer

Standard

ASTM D4040-99, ISO 12644, DIN 53222 standard
