It is developed for analysing the weight loss by combustion and pyrolysis (TGA) of materials. It includes several parts, such as balance, heating furnace, programmed temperature control system, recording system, etc. It can observe the change of sample mass with temperature and time during the process of heating up, constant temperature or cooling down, and it is equipped with pyrolysis material condensation collection device. It is widely used in research and development, process optimisation and quality control in the fields of plastics, rubber, coatings, pharmaceuticals, catalysts, inorganic materials, metal materials and composites.
