Low-temperature Kinematic Viscometer
Summary
The instrument is designed and made as per the industrial standard of People’s Republic of China SY/T5651 Technical Condition for Kinematic Viscosity of Petroleum Products. It is suitable to determine the kinematic viscosity of liquid petroleum products (Newton liquids) under a constant temperature (low temperature) as per the national standard of People’s Republic of China GB/T265 Petroleum products-Determination of kinematic viscosity of and calculation of dynamic viscosity.
I. Main technical features
1. This instrument is a kind of specially made instrument suitable to test the low temperature kinematic viscosity of petroleum oils. It adopts advanced technology of compressor refrigeration. The minimum temperature can reach -70℃.
