1. It is suitable to determine kinematic viscosity of liquid petroleum products (Newton liquids) at a certain temperature.

The instrument is designed and made as per the Industry Standard of People’s Republic of China SY/T5651 “Technical Requirements for Petroleum Products Kinematic Viscosity Tester”. It is suitable to determine kinematic viscosity of liquid petroleum products (Newton liquids) at a constant temperature as per the National Standard of People’s Republic of China GB/T265 “Test Methods for Kinematic Viscosity of Petroleum Products and Calculation of Dynamic Viscosity”.

I. Main technical characteristics

1. It adopts advanced compressor refrigeration technologies, so the lowest controlling temperature can be -70 °C and the temperature controlling accuracy can be ±0.1°C.

2. There is a fluorescence light device at the upper section of observation window, so it is clear to see the scale on the capillary viscometer and it is convenient to read the reading.

3. It can make test for two samples at the same time and it is efficient.

4. It adopts integrated floor-standing structure, so it looks good and it convenient to move.

5. It uses an electric stirring device, so the temperature in the bath is uniform.
