title: A proportional controlled thermoregulator circuit of simple design.
abstract: This paper describes a proportional controlled thermoregulator circuit. The instrument controls D.C. current in the heating device, precluding the introduction of radiated interference by the heater. This circuit is capable of regulating the temperature of a typical decerebrated cat to within 0.1 degrees C. A dual channel temperature regulator can be constructed for about $ 300.
