Description of the Product
The Viscosity Measuring Analyzer Laboratory Viscometer, available in models YR05855 and YR05856, represents a pinnacle of precision in the field of rheological analysis. Designed for robust laboratory environments, this viscometer boasts a wide measuring range and user-friendly functionality. The YR05855 model operates at rotational speeds of 3/6/12/30/60 rpm, while the YR05856 extends these capabilities from 0.3 up to 60 rpm, allowing for flexibility in various testing scenarios. Both models are built to cater to the most demanding viscosity measurements, with the YR05855 capable of measuring from 1 to 100,000 mPa.s and the YR05856 from 1 to an impressive 6,000,000 mPa.s.
Precision is at the forefront of these models’ design, with measurement errors for Newtonian liquids being only ±0.5% for the YR05855 and ±1% for the YR05856. To enhance accuracy and reliability, these viscometers include 1-4# standard rotors, with an optional 0# rotor for measurements below 10 mPa.s. This adaptability ensures that laboratory professionals can trust in consistent results across a wide range of applications.
