Spesifikasi BitU-Visc 120 Omnitek BitU-Visc Automatic Viscometry System


The Omnitek BitU-Visc is a programmable, fully automatic kinematic viscometer specially designed to handle highly viscous samples at high temperatures. The system can process samples with viscosities ranging up to 120,000 mm2/s, up to 150 C. 

Test Method

Kinematic viscosity characterizes flow behavior. This method covers the procedure for the determination of kinematic viscosity of liquid asphalts, road oils, and distillation residues of liquid asphalts at high temperatures. 


  • Applicable for fuels, base oils, formulated oils, highly viscous samples like vacuum residues, additives, crude oils, waxes, heavy fuel oils, polymers, asphalts, etc. 
  • Meets all ASTM, EN, ISO, DIN, AASHTO T201 and standards related to kinematic viscosity standards
  • Extremely accurate temperature control
  • Extremely accurate flow-time measurement independent of fluid type
  • Viscometer filling by vacuum method
  • Innovative and efficient viscometer tube cleaning allowing cross contamination free operation
  • Easy viscometer tube exchange
  • Chemically resistant to an extended range of fluids and solvents
  • Compact design


Conforms to the specifications of: 

ASTM D445, D446, D2170; AASHTO T201; IP 71; ISO 3104, ISO 3105; DIN 51562; FTM 791-305; NF T 60-100
