ISO 5660 Cone Gauge Calorimeter

Application

The oxygen consumption calculated from the oxygen concentration in the combustion product gas stream and the heat release rate of the combustion products when burning, the material's heat release rate is also the most important parameter in the material combustion performance, and the heat release rate in the material combustion process is measured accurately. For the prediction of fire hazards and its fire-retardant treatment is extremely important.
