The manufacture of the instrument conforms to the requirements specified in the industry standard SY/T5651 “Technical Conditions for kinematics Viscosity Tester of Petroleum Products” of the People’s Republic of China. This instrument is suitable for the determination of the kinetic viscosity of liquid petroleum products (referring to Newton liquid) at a constant temperature (low temperature) under the provisions of the People’s Republic of China standard GB/T265 “Kinetic viscosity determination method for petroleum products and dynamic viscosity calculation method”.

I. Main technical features

1, the temperature of the constant temperature bath is controlled by the temperature controller, and the cooling and heating two parts compensate each other to achieve the heat balance, so that the control bath temperature maintains a certain precision.

2, the top of the constant temperature bath is provided with LED lighting device, which makes the scale of the capillary viscometer in the constant temperature bath clearer and more convenient for reading.

3, the instrument can be installed at the same time two samples for testing. The constant temperature bath is equipped with a stirring motor, so that the temperature in the whole constant temperature bath is uniform.
