Thermo Scientific™ HAAKE™ Falling Ball Viscometer C only requires a stopwatch for viscosity measurement without connecting a power source. The measurement accuracy of HAAKE falling ball viscometer C is the highest among all viscometers, especially with the precise temperature control of the circulator. It can accurately measure the viscosity of transparent Newtonian liquids and gases. HAAKE falling ball viscometer C also meets the requirements of German DIN 53015 and ISO 12058 standards, and has been accepted as an official reference instrument.
