TGA High Temperature Vacuum Weight Loss And Pyrolysis Analysis System
product introduction：
The product was developed to analyze the weight loss and pyrolysis weight (TGA) of materials burned in vacuum or atmosphere. It includes several parts, such as balance, heating furnace, temperature control system, recording system, etc., which can observe the changes of sample quality with temperature, time, vacuum degree and atmosphere state in the process of temperature rise, constant temperature or temperature drop. It is widely used in the research and development, process optimization and quality control of plastics, rubber, coatings, pharmaceuticals, catalysts, inorganic materials, metal materials and composite materials.

Configuration details
| 1. Annular arrangement is adopted for furnace heating to reduce interference;
2. The weight sensor is made of precious metal ni-cr alloy, which has the advantages of high temperature resistance, oxidation resistance and corrosion resistance. 3. Separate the power supply and circulating heat dissipation from the main engine to reduce the influence of heat and vibration on the micro-thermal sensor; 4. Adopt upper electric pull structure, easy to install and operate; 5. Use the water bath thermostatic device to isolate the thermal influence of the heating furnace body on the cabinet and micro thermal balance; |
