Instead of a jewel bearing, these devices are equipped with a special ball bearing technology, characterized by their high robustness. Predestined for applications with very high sample throughput, frequent spindle changes, operation in harsher environments, or even frequently changing device locations, ROTAVISC delivers fast and accurate results for both simple and demanding viscosity measurements. Intuitive menu navigation awaits you via the generous 4.3" TFT display, with a digital leveling feature that supports the correct setting of the starting condition. Recurring tasks are facilitated by the simple ramp function. The accuracy of the ROTAVISC rotary viscometers for Newtonian and non-Newtonian liquids is +/- 1% of the measuring range, with reproducibility of +/- 0.2%. With ROTAVISC, you have a viscometer in which you can adjust the speed steplessly, as well as specify programs or individual speed levels. The viscosity-measuring range is 800 - 320,000,000 mPas.INCLUDED: The IKA ROTAVISC SBS hi-vi II Complete includes: - Power Cord - Two Year Manufacturer's Warranty
