Introduction
The instrument 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 liquid) at a certain temperature. It is also in accord with requirements of SY/T 5651 "Technical Condition for Petroleum Products Kinematic Viscosity Tester".
Characteristics
1. It mounted with digital temperature controller
2. The temperature controlling precision is up to ±0.01°C.
3. The testing bath is made of hard glass, equiped with electric stiriing device, that can keep the equilibrium temperature in the bath.
4. Two bases, inner and outer bath, could keep a good heating reservation.
