The advantages of using diodes as thermal sensors in solution thermochemistry are discussed and a simple, low-cost circuit
for the use of diodes as temperature sensors is reported. In preliminary studies, the titration of TRIS and hydrochloric acid
is used to compare the precision of thermistors and diodes in thermometric titrimetry. Several systems are assayed at various
temperatures by enthalpimetric methods to illustrate the advantages of diodes as sensors for monitoring thermal methods capable
of being used in quality control system.
