The invention relates to a trace sol viscosity measuring device based on light absorption and scattering and a use method thereof. The device comprises a semiconductor laser, a sol sample, a water bath heater and a high-intensity light power meter. The viscosity of the sol is different, light absorption and scattering are different, and the viscosity of the sol sample can be measured by detecting the power of the laser penetrating through the sol sample. The method can be used for real-time on-line monitoring of the change of the viscosity state of the sol in the sol preparation process, and is also suitable for measuring the viscosity of a trace sol sample. The structure is simple, and the operation is convenient. 本发明涉及一种基于光吸收及散射的微量溶胶粘度测量装置及其使用方法，该装置包含半导体激光器、溶胶样品、水浴加热器、强光光功率计。溶胶粘度不同，对光的吸收和散射不同，通过检测透过溶胶样品的激光功率可实现对溶胶样品粘度的测量。此方法可以用于实时在线监测溶胶制备过程中其粘度状态的变化，也适用于微量溶胶样品粘度的测量。同时具有结构简单、操作方便等优点。
