CONE CALORIMETER What is it A cone calorimeter is a device used to measure the thermal behavior of small samples of materials in their condensed phase. Its extensive use is in fire safety engineering, where it is employed to study how different materials burn. The calorimeter can measure the heat release rate, smoke generation rate, ignition time, oxygen consumption status, carbon monoxide, carbon dioxide generation, and mass loss rate of the given material sample. A cone calorimeter is a scientific instrument used to measure the heat release rate and smoke production of materials when they are exposed to an external heat source. This information is valuable for evaluating the fire performance of materials and products, and for developing fire safety standards and codes. The cone calorimeter consists of a small, sealed chamber with a cone-shaped opening at the top. A sample of the material to be tested is placed in the chamber, and an external heat source is applied to the material through the cone-shaped opening. The heat release rate and smoke production of the material are measured using sensors within the chamber.
