BIUGED supply a series of different viscosity standard oils which can bring

convenience for calibrating your viscometers or flow cups. They are Newton liquid,

with a perfect stability, hydrophobic and damp-proof. Good physical inertia and low

surface tension. They can be kept and used for a long time.

Every bottle of standard oil has been calibrated by SOUTH CHINA NATIONAL

CENTER OF METROLOGY , and comes with a calibration certificate report which

calibrates kinetic viscosity（cP value）and kinematic viscosity （cSt value）, and

has a very high reliability and accuracy.

Notice:
     ① The tested value of below table is tested at 25℃.

②   For every bottle standard oil, the fact viscosity value should be taken as final by calibration

certificate report.

③ The period of validity for viscosity value of standard oil is one year, it should be recalibrated

every year
