1. A system for measuring temperature-dependent parameters of a liquid sample, said system comprising:

  • a base portion made of a material exhibiting excellent heat transfer characteristics;

    detecting means for detecting the temperature of said base portion;

    a disposable sample card for confining a predetermined volume of said liquid sample in intimate contact with said base portion wherein, after a period of time, said liquid sample assumes the temperature of said base portion;

    electrode means immersed within said predetermined volume of said liquid sample; and

    means connected to said electrode means and said detecting means for producing a signal indicative of the temperature-dependent parameter being measured.
