The authors constructed an apparatus for the determination of the 'flow point' which H.R Lillie suggested as the reference temperature for the viscosity of 105 poises. They investigated several types of electronic amplifiers, adjusted the support of the heating coil and calibrated the apparatus by a series of selected curves. The reached practically the same accuracy in the definition of the investigated temperature as H.R Lillie.
