The Thermo Scientific HAAKE Falling Ball Viscometer C enables a precise and accurate viscosity measurement of transparent Newtonian liquids and gases, using only a stop watch and no power connection. The measuring accuracy of this falling ball viscometer is among the highest available in any type of viscometer, particularly when accompanied with the precise temperature control of a circulator. The HAAKE Falling Ball Viscometer C also meets the requirements of the ISO 12058 standard, and is accepted as an official reference instrument.
