Product Description
The YG1956 and YG1957 rotational viscometers are cutting-edge instruments designed for precise viscosity measurements. Featuring a user-friendly 5-inch color touch screen, these devices offer intuitive control and display capabilities, making them ideal for laboratory environments where accuracy and ease of use are paramount.
With speeds ranging from 3 to 60 r/min for the YG1956 model, and a broader range from 0.3 to 60 r/min for the YG1957, these viscometers cater to various testing needs. The measurement range is notable, with the YG1956 capable of measuring between 1 and 100,000 mPa.s and the YG1957 extending this range dramatically up to 2,000,000 mPa.s.
Both models come equipped with a 0# rotor for low viscosity and four standard rotors for a wide range of measurement capabilities. Complementing this is the automatic scanning function, which intelligently recommends the best rotor and speed combination based on the sample’s viscosity. The viscometers also boast a temperature measurement function, ensuring that the measurement is consistently accurate, regardless of external conditions.
Further enhancing their utility, these viscometers include features such as real-time viscosity curve display, data output interfaces, and the ability to save up to 30 groups of measurement programs and results. This ensures that you can tailor settings to specific testing requirements and easily review past results for ongoing analysis. Their compact dimensions (300 × 300 × 450 mm) and compatibility with both 110 V and 220 V power supplies make them versatile instruments suitable for any laboratory setting.
