General Description :
Apparent viscosity of unfilled asphalt is evaluated by a rotational viscometer which measures the torque generated by a calibrated spindle rotating at a selected speed into a bitumen sample heated at precise temperature in the range between ambient temperature to 260° C. The measured relative resistance to rotation is converted, by a factor, in viscosity units, cP or mPa.s.
Rotary viscometer matches ASTM D2196, ASTM D4402 and AASTHO T316 requirements.

Rotational viscometer supplied with stand, boss head, spindle protection, spindle rack, power supply cable.
100-240V, 50-60 Hz, 1Ph
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.
Temperature control unit with temperature range from ambient plus 5°C to 300°C.
220-240V, 50-60Hz, 1 ph
