Description of the Product
The Lab Rotational Viscometer models YR05853 and YR05854 are engineered to offer high accuracy and reliability for viscosity measurements in both research and industrial applications. These models are equipped with a user-friendly 5-inch color touch screen, allowing for seamless operation and navigation through the device’s features. They are designed to accommodate a range of speeds and viscosities, making them versatile tools for any laboratory.
With the **YR05853**, users can measure viscosities from 1 to 100,000 mPa.s, while the **YR05854** offers an expanded measuring range from 1 to 2,000,000 mPa.s. Both models come standard with rotors numbered 1 through 4 and a 0# rotor for low viscosity measurements. The viscometers boast a measurement error of only ±2% for Newtonian liquids and promise a repetitive error of merely ±1%, ensuring precision in every test.
