Product Description
The high-temperature viscometer models YR05843, YR05844, YR05845, and YR05846 from Kalstein represent a breakthrough in viscosity measurement technology. Equipped with a liquid-crystal display, these devices offer clear and accurate reading of measurements, making them incredibly user-friendly. These viscometers provide a range of speeds from 0.5 to 100 r/min, totaling 18 variable speeds, allowing for precise control over the measurement process to suit diverse applications.
The rotor selections are customizable according to the model, featuring options like 18, 25, 31, and 34 for the YR05843, and standard configurations of 21, 27, 28, and 29 for the other models. This diversity in rotor choice accommodates a broad range of viscosity measurements. Each model boasts a remarkable measuring range, with the YR05843 capable of handling viscosities from 3 mPa.s to 1.6 million mPa.s, while the YR05846 can measure between 400 mPa.s and 16 million mPa.s. The precision of these viscometers is underscored by their test and repetitive errors, which are maintained at ±3% and ±1.5% respectively for Newtonian liquids.
Temperature control is another vital feature of these viscometers, offering a control range from room temperature plus 10°C to 250°C, with an optional extension to 300°C. Additionally, they ensure a control accuracy of 0.1°C, crucial for experiments where thermal conditions affect viscosity. The ability to interface directly with a printer further enhances their functionality, making data collection and analysis seamless.
