Rotational Viscometer LBN-RV112 uses a coaxial center structure that requires only 8 to13 ml of sample, delivering fast response and precise temperature control for high-temperature viscosity testing. It offers PC-based calibration for improved accuracy and repeatability across the full measuring range. Equipped with an LCD display that shows results directly in English for easy operation. Integrated microcomputer control and a stable stepper motor ensure smooth speed and reliable test performance. Our Rotational Viscometer supports wide material testing, including oils, polymers, and coatings.
