Product Description
The latest models of laboratory viscometers, the YR05855 and YR05856, set a high standard in viscosity measurement with a precise and versatile approach. These instruments are engineered to deliver cutting-edge accuracy and efficiency for laboratories handling Newtonian and non-Newtonian liquids. The YR05855 features a rotating speed ranging from 3 to 60 revolutions per minute (r/min), while the YR05856 expands this range from 0.3 to 60 r/min. This versatility allows for detailed analysis across various fluid dynamics scenarios, ensuring comprehensive viscosity assessments.
The measuring range of these viscometers further underscores their professional aptitude. The YR05855 measures from 1 mPa.s up to 100,000 mPa.s, while the YR05856 extends this to an impressive 1 to 6,000,000 mPa.s, accommodating diverse applications. Standard rotors #(1-4) are included, with the option for a #0 rotor to enhance sensitivity for lower viscosity measurements. Accuracy is paramount; thus, the models promise a measuring error margin of ±0.5% for YR05855 and ±1% for YR05856, with repetitive error rates held at ±0.25% and ±0.5% respectively.
Both models support a timer function, aiding precise measurement controls. The viscometers operate at either 110V / 60Hz or 220V / 50Hz, facilitating use across various geographic regions. Encased in dimensions of 300 x 300 x 450 mm, they are compact yet robust enough for consistent laboratory operations.
