Abstract (en)

[origin: WO9714949A1] An apparatus for measuring viscosity of liquids includes an external chamber (10) which encloses an internal chamber/duct (20) having an inlet (21) and an outlet (22). Internal chamber (20) houses a fan (30) for forcing air through the duct, a first heater (40) for heating air within the duct, a second heater (81/82) for heating air externally of the duct, a thermal ballast (50) for maintaining the temperature of the air in the duct constant, and a viscometer (72) for measuring viscosity of liquids.
