ASTM D2171 Apparatus for Viscosity of Asphalts

KN-2171 Apparatus for Viscosity of Asphalts

Overview

    KN-2171 Apparatus for Viscosity of Asphalts conforms to ASTM D2171 Standard Test Method for Viscosity of Asphalts by Vacuum Capillary Viscometer. The viscosity at 60℃ characterizes flow behavior and may be used for specification requirements for cutbacks and asphalt binders. This time is measured for a fixed volume of the liquid to be drawn up through a capillary tube by means of vacuum, under closely controlled conditions of vacuum and temperature. The viscosity in Pascal-seconds is calculated by multiplying the flow time in seconds by the viscometer calibration factor.

Features

1. Functions of storing and time measuring

2. Automatic regulation of the temperature and vacuum degree

3. Automatic timing function

4. LCD screen with easy operation interface

5. High precision pressure sensor to measure the vacuum degree

6. Be able to control the parameters of three groups of capillary viscometers and calculate the viscosity value of each section. Then the tester will pick the valid data as per the standard requirements, and calculate the average value.

7. Equipped with printer, be able to print the test result and historical data
