Large Cone Calorimeter with Variable Atmosphere

• 

The Large Cone Calorimeter with Variable Atmosphere is designed to measure the heat release rate of materials based on the oxygen consumption principle. You can accurately determine material combustibility, ignition time, mass loss rate, and derived data such as effective heat of combustion and specific extinction area. During testing, samples are placed on a loading unit, heated, and ignited with an electric spark. Combustion gases are collected through exhaust and adsorption ducts, and parameters such as gas concentration, pressure, temperature, and smoke density are automatically recorded. This instrument provides a safe, fast, and reliable method for material development, fire research, and quality control.
