Product Description
The high temperature viscometers YR05843, YR05844, YR05845, and YR05846 are state-of-the-art devices designed to deliver accurate viscosity measurements under high thermal conditions. These viscometers are equipped with a **liquid-crystal display** which provides clear readings and easy operational control, ensuring users can manage the measurement process efficiently. The models can operate at **18 distinct speeds**, ranging from 0.5 to 100 rotations per minute, allowing for precise control over the measurement process.
Each model features different rotor configurations tailored to specific viscosity ranges, with the YR05843 supporting rotors 18, 25, 31, and 34; and models YR05844, YR05845, and YR05846 using rotors 21, 27, 28, and 29 as standard. These differently configured rotors enable the measurement of a broad spectrum of viscosities, from low (3 mPa.s) to ultra-high (16 million mPa.s). Moreover, these viscometers boast a remarkable **temperature control range** from room temperature to 250℃, extendable up to 300℃, thereby accommodating applications that require stringent thermal conditions.
The devices ensure measurement accuracy within ±3% for Newtonian liquids, and replicate results with an error margin of just ±1.5%. Such precision underscores their reliability in scientific and industrial applications alike. Furthermore, they are equipped with a print interface, facilitating efficient documentation and data collection.
