Heat Flow Meter

Heat Flow Meter

The Heat Flux Meter is a precision instrument used to measure the heat flux density. It accurately captures and records the amount of heat flowing through the surface of a material, typically used in thermal conductivity, heat exchange efficiency assessments, and the testing of material thermal properties. Heat flux meters are widely applied in fields such as building energy efficiency, material science, electronics cooling, and environmental testing. By measuring heat flux density, the instrument provides critical thermal management data, helping engineers optimize designs and improve system efficiency. Its operation is based on the thermoelectric effect, where sensors detect the temperature difference across the material surface and calculate the heat flux.
