Abstract: Reference thermocouple junctions are maintained at a constant temperature by an insulated housing which surrounds the junctions. A heating element is contained within the housing. Temperature sensing elements disposed within and outside the housing control the heating element. The thermocouple junctions, internal sensing element and heating element can be secured to a metal block within the housing.
