Product Description
The Touch Screen Brookfield Viscometer models YG0773 and YG0774 are cutting-edge devices designed to measure viscosity with precision and versatility. These viscometers are equipped with an intuitive touch screen interface, allowing for seamless operation and accurate readings. Essential for laboratories working with liquids of varying viscosities, these models stand out due to their advanced features and reliable performance.
The YG0773 model offers a measuring range that accommodates a wide variety of viscosities, utilizing rotors 1-4 to measure 10-2,000,000 mPa.s. Optional rotors expand this capability, with ULR measuring from 1-1000 mPa.s, and rotor 18 measuring from 3 to 10,000 mPa.s. In contrast, the YG0774 model enhances this range even further, enabling measurements from 10-6,000,000 mPa.s with standard rotors and 1-6,000 mPa.s with the ULR rotor. Both models support optional rotors for even more specific ranges.
This viscometer’s operational efficiency is evident through its speed options, offering a variable range from 0.3 to 100 r/min for a combination total of 998 speed settings. The error margin is remarkably low, at ±1% for Newtonian liquids, with a repetitive error of ±0.5%. These characteristics, combined with the device’s data interfaces and power supply adaptability (110V-240V), solidify its reliability across diverse laboratory environments.
