title: DC proportional heater-cooler temperature controlled for physiological research.
abstract: A DC proportional temperature control circuit for driving resistive heaters and Peltier thermoelectric devices in physiological research is described. The instrument, supplying +/- 12.5 V DC at 8 A is designed for temperature control of anesthetized animals, generation of hot or cold thermal stimuli, and control of thermal environments.
