The manufacture of the instrument conforms to the requirements specified in the industry standard SY/T5651 “石油产品运动粘度测定仪技术条件” 中华人民共和国. 本仪器适用于液体石油产品动力粘度的测定 (指牛顿液体) 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”.

我. 主要技术特点

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.
