Emc thermal conductivity
WebThe C-Therm Trident Thermal Conductivity Platform is a flexible, rapid, non-destructive, highly sensitive and cost effective instrument that can directly measure thermal conductivity and thermal effusivity of a wide variety of samples, easing the process of determining thermal resistance and thermal conductance. WebWhen an electric current is passed through a circuit of a thermocouple, heat is generated at one junction and absorbed at the other junction. This is known as the Peltier effect : the presence of heating or cooling at an electrified junction of two different conductors.
