Product Description
The high-temperature viscometers from Kalstein, specifically models YR05843 to YR05846, represent cutting-edge technology in viscosity measurement. These instruments are designed to deliver precise and reliable data across a wide range of viscosities and temperatures. Equipped with a liquid-crystal display, these models provide clear and easy-to-read results, ensuring that users can monitor and adjust parameters as needed.
These viscometers offer remarkable versatility with 18 different speeds, ranging from 0.5 to 100 r/min. This range allows users to select the optimal speed for their specific sample and testing requirements. The standard rotor configuration includes rotors 21, 27, 28, and 29, which accommodates a broad spectrum of viscosity measurements from 50 mPa.s to as high as 16 million mPa.s.
The precision of these viscometers is further enhanced by their error margins, which are ±3% for test error and ±1.5% for repetitive error when used with Newtonian liquids. Additionally, the precise temperature control range from room temperature plus 10℃ to 250℃ or optionally up to 300℃, with an impressive accuracy of 0.1℃, ensures reliable results even under challenging conditions.
