Product Description
The Laboratory Viscometer Model YR05855 and YR05856 by Kalstein are advanced instruments designed to measure viscosity with exceptional accuracy and reliability. Equipped with various rotational speeds, these viscometers offer flexibility for diverse laboratory applications. The YR05855 has a rotation speed range of 3 to 60 r/min, while the YR05856 extends from 0.3 to 60 r/min, providing users with comprehensive options for viscosity analysis.
With their measurement range, the YR05855 spans from 1 to 100000 mPa.s, whereas the YR05856 extends up to 6000000 mPa.s. These devices are suitable for a wide variety of substances, from Newtonian liquids to complex mixtures, ensuring precise readings with minimal error. Users can select from standard rotors 1-4#, and an optional 0# rotor for measurements below 10 mPa.s is available to enhance accuracy further.
The viscometers are meticulously designed to minimize errors, with the YR05855 showcasing a measuring error of ±0.5% for Newtonian liquids and a repetitive error of ±0.25%. Meanwhile, the YR05856 measures with an error margin of ±1% and a repetitive error of ±0.5%. Additionally, both models feature a timer function, ensuring controlled and consistent measurement processes.
