Kinematic Viscometer for Bitumens Bit U-Visc


The Bit U-Visc system provides users with completely automatic heating, sampling, measurement and cleaning of high viscosity samples such as bitumen and vacuum residue. The instrument was designed to be versatile and flexible, yet easy to use to cover the hardest applications. Different models are available with 1 or 2 tubes, allowing for the analysis of a wide range of viscosities and sample types.


The tubes are based on the well-known and proven , Ubbelohde design. Using specially designed thermal sensors, these tubes allow the detection of fully opaque fluids without any problems or limitations and eliminate the need to use the reverse flow tubes common in bitumen testing. The standard configuration offers viscosity measurement up to 165 ºC, and sample preheating up to 200 ºC.
