ABSTRACT:
A heat-generating element and a fluid temperature measuring element are immersed in a molten or gelled fluid sample to measure continuously both temperature .SIGMA.w of the said heat-generating element and fluid temperature .THETA..infin. during the cooling or heating of the fluid sample at one or several constant cooling or heating rates. An abrupt change in .THETA.w-.THETA..infin. value is detected to obtain the practical gel-point temperature of a characteristic gel-point temperature, which is defined as the extrapolated gel-point temperature at a cooling or heating rate of zero.
