Product Description
The Touchscreen Brookfield Viscometer YR05858 and YR05859 models are cutting-edge instruments designed for precise viscosity measurements. These viscometers feature a user-friendly touchscreen interface, offering intuitive control for measuring the viscosity of a wide range of substances. With an adjustable speed range of 0.3 to 100 revolutions per minute and a total of 998-speed options, these instruments provide a high degree of flexibility and precision.
Both models include rotors L1 to L4 as standard and support enhanced ultra-low viscosity adapters (ULR) and small sample adapters as optional accessories. The measurement range varies to accommodate different viscosities: for rotor 1-4, ranges extend from 10 to several million millipascal-seconds (mPa.s), depending on the model. These viscometers are equipped with a measurement error margin of ±1% for Newtonian liquids, ensuring reliable data output via RS232 interfaces. Crafted to comply with every laboratory requirement, the viscometers offer seamless performance and flexibility.
