Viscometers are indispensable instruments in many scientific and technical fields of application for determining the flow resistance of liquids. In the Kalstein catalog, we find four representative and state-of-the-art models in the range of digital viscometers.
YR05861 // YR05863: Brookfield rotary viscosity testers
The YR05861 and YR05863 models of Kalstein’s digital viscometers are designed with high accuracy to measure viscosity ranges from 1 to 2,000,000 mPa-S. With an easy-to-read LCD display, these viscometers feature varied spindle specifications, including 0, 1, 2, 2, 3, 4 options for the YR05861 model and a wider range for the YR05863. https://kalstein.ee/product/digital-rotating-viscometer-brookfield-viscosity-tester-yr05861-yr05863/
The rotational speed of the spindles is varied, allowing users to select the appropriate rotational speed or number of axes thanks to their automatic switch. The measurement accuracy of these models is ±1%, while the measurement repeatability is ±0.3%. A relevant factor in these models is the stable cursor, which facilitates accurate readings by being basically stable.
Laboratory Viscosimeter Viscosity Analyzer YR05855 – YR05856
Available in versions YR05855 – YR05856, these laboratory viscometers are capable of measuring ranges from one million to two million mPa-s/cps, with a measurement tolerance of ±2%. They include specified spindles from No. 0 through No. 4, and with the additional feature that, as the number of spindles increases, the measurement value also increases. https://kalstein.ee/product/viscosity-measuring-analyzer-laboratory-viscometer-yr05855-yr05856/

Industrial and Rotational Digital Laboratory Viscometer
The models YR05857 and YR05858 of the Kalstein family feature a wide measuring range from 1 mPa.s to 6,000,000 mPa.s. Equipped with an RS232 interface, these devices ensure high measuring accuracy with a tolerance of ±2%. They offer different rotation speeds, with all the conveniences to facilitate their use in industrial environments. https://kalstein.ee/product/industrial-digital-laboratory-viscomsimeter-yr05857-yr05858/
Highly versatile and accurate, the YR05853 and YR05854 models are capable of measuring viscosity ranges from 1 to 100,000 mpa.s with a measurement tolerance of ±2%. They include an RS232C interface and a temperature probe, as well as CD editing software. They also feature a fully loaded strip-type cursor that is displayed when reading basically stable. https://kalstein.ee/product/lab-rotational-viscometer-yr05853-yr05854/
In summary, Kalstein digital viscometers offer a combination of high accuracy and ease of operation, enabling reliable viscosity measurement in all laboratory and field operations. They have become a highly recommended choice for all professionals looking for advanced functionality in viscosity measurement.
