Robust Rotational Viscometer
Versatile viscometer line said to offer robust measurement, repeatability and reporting.
The byko-visc Rotational Viscometer from Paul N. Gardner USA is for precise measurement results with each test condition recorded for detailed results analysis and review. This precision is said to be repeatable day-to-day and instrument-to-instrument thanks to BYK-Gardner’s rigorous quality control. An ISO 17025 calibration certificate is supplied with each instrument to confirm this performance.
Joining the BYK-Gardner offering of viscosity instruments — flow cups, bubble viscometers, the digital stormer viscometer, and cone and plate viscometers — the byko-test RT now brings a comprehensive solution for customers’ QC needs.
The byko-visc RT offers an intuitive navigation, a multitude of control options, and a large capacitive color touch-screen display, which includes preset buttons to quickly recall often used measuring parameters. These benefits reportedly reduce operator time.

The byko-visc RT features an easy snap-on spindle attachment saving valuable operator time while protecting the instrument, and an adjustable stand to allow the user to easily raise and lower the viscometer head. The instrument is ready right out of the box.
The new line is also compatible with many other rotational viscometer models in terms of results, measurement parameters, and accessories, like spindles. This will also allow users to seamlessly transition to a byko-visc RT system.
