Purpose:
PT-D445-265G Low Temperature Kinematic Viscosity Tester is designed and made as per the National Standard GB/T265 "Test Methods for Kinematic Viscosity of Petroleum Products and Calculation of Dynamic Viscosity". It is suitable to determine kinematic viscosity of liquid petroleum products (Newton liquids) at a certain temperature. It is also in accord with SY/T5651 "Technical Condition for Petroleum Products Kinematic Viscosity Tester".
Technical Features
- With advanced compressor technology, the system can bring down the temperature into -70°C while the temperature precision can reach ±0.1°C.
- There is fluorescent lamp system on the glass window, so the capillary viscometer in the constant bath could be clearly read; it makes the operation more convenient.
- It can load two samples simultaneously, so the system can do two tests at the same time.
- Top loading design to make the instrument compact and flexible.
- Electric stirrer is installed to make the inside temperature even.
