    • The temperature control unit consist of a heating chamber that is used to work  in conjunction with rotary viscometers at high temperatures.  Viscosity of solid road unfilled asphalts has to be measured at  temperatures ranging from 34°C to 260° according to the Specifications of ASTM D4402. The heater contains the container with sample  in which a suitable spindle is immersed and driven by the rotary viscometer to measure viscosity. A digital microprocessor control unit grants the required accuracy of test temperature.
