Summary
  The instrument is designed and made as per the national standard of People’s Republic of China GB/T1841 and ASTM D2170 Standard Test Method for Viscosity of Polyolefin Resin Solution. It is used to determine the viscosity of decahydronaphthalene solution of polythene and polypropylene at the stipulated temperature. The instrument can also be used to determine the viscosity of asphalt at the stipulated temperature as per the industrial standard of People’s Republic of China T0619 Asphalt Kinematic Viscosity Test (Capillary Viscometer Method).
