B085-21 Rotational Viscometer High Performance

( Bitumen )
  • EN 13302
  • ASTM D2196
  • AASHTO T316
  • ASTM D44022

ROTATIONAL VISCOMETER HIGH PERFORMANCE

Test Method: Determines the dynamic viscosity of a substance by the rotation of a specified spindle within the sample at the speed giving the maximum torque reading on the viscometer. The resulting torque reading is used to calculate the viscosity of the substance.

Supplied as a complete system in a very robust carrying case, including a complete set of standard spindles with storage rack (6 spindles) spindle guard and calibration certificate.

Power supply: 230V 50-60Hz 1ph
Dimensions: 530x430x280 mm
Weight: 11 kg approx.


MAIN FEATURES

  • Wide viscosity range.
  • High accuracy ± 1% on full scale.
  • High repeatability ± 0.2%.
  • Temperature sensor PT 100 included.
  • High temperature precision ± 0.1 °C.
  • Direct readout on graphic display.
  • Full data display

THE VISCOMETER B085-21 CAN BE USED IN TWO DIFFERENT METHODS:
Method A:
B085-21 and B085-29 are needed
Method B:
B085-21, B085-29 and accessories are needed
