Figure 7 is a schematic of the relationship between components in automated thermometric titration system. Thermometric and magnetic based biosensors are rare. This is an adaptation of a classic thermometric titration application (VanDalen and Ward, 1973). Redox reactions are normally strongly exothermic, and can make excellent candidates for thermometric titrations. It cannot be used as a thermometric substance near that temperature. Such cases supply what are called "thermometric bodies", that allow the definition of empirical temperatures. During recent decades, many thermometric techniques have been developed. Non-aqueous acid-base titrations can be carried out advantageously by thermometric means. The WPF-89-1 is the thermometric version of the PF-89. Thermometric titrations of silver nitrate with halides and cyanide are all possible. Weakly dissociated acids yield sharp thermometric endpoints when titrated with a strong base. It is not a thermometric material in the usual sense of the word. Thermometric titrimetry offers a rapid, highly precise method for the determination of aluminium in solution.
