A Digital Redwood Viscometer is a laboratory instrument used to measure the kinematic viscosity of petroleum products, such as oils, fuels, and bitumen’s, by determining the time it takes for a liquid to flow through a standardized orifice under gravity. It adheres to international standards like IP 70 (Institute of Petroleum) and IS 1448, ensuring consistent results for quality control in oil refineries, research labs, and educational institutions. The “digital” aspect refers to modern enhancements like electronic temperature controllers, indicators, and regulators, which provide precise control and readout compared to traditional analog models.
