The U-Visc is engineered for a wide range of applications, from petroleum and lubricant analysis to academic research and industrial automation. It is suitable for testing fuels, base oils, formulated lubricants, and petrochemical samples. Industries that benefit include refineries, additive manufacturers, condition monitoring laboratories, research facilities, and quality control centres. Its flexible sampling and temperature control make it suitable for use with dilute solutions, industrial oils, and other petroleum-based products.
The U-Visc system is controlled via dedicated PC software compatible with Windows 7 or higher, offering comprehensive data management, process monitoring, and reporting functions. It allows multiple instruments to be managed from one PC, ensuring scalability for automated laboratories. Data can be easily exported via USB or RS-232C connection, and the interface supports seamless integration with laboratory information management systems (LIMS).
