A heat flow meter is an instrument used to measure the surface temperature of an object. Its principle is based on the law of heat conduction and thermoelectric effect.

The law of heat conduction states that at a constant temperature, the rate at which heat is conducted from a high temperature region to a low temperature region is proportional to the temperature gradient. The heat flow meter uses this law to calculate heat flux by measuring the temperature distribution on the surface of an object The working principle of a heat flow meter is to use the thermocouple principle to establish a heat flow field between two thermocouples at different temperatures, calculate the heat flow at standard temperature, and measure the thermal conductivity and thermal conductivity of materials.
