TGA 103A ThermoGravimetric Analyzer
Working principle
Thermogravimetric analysis (TG, TGA) is a method of observing the changes in the mass of a sample with temperature or time during heating, constant temperature, or cooling processes, with the aim of studying the thermal stability and composition of materials.
The DZ-TGA103A thermogravimetric analyzer is widely used in research and development, process optimization, and quality monitoring in various fields such as plastics, rubber, coatings, pharmaceuticals, catalysts, inorganic materials, metal materials, and composite materials.
Structural advantages
1. The furnace body heating adopts a double row winding of precious metal platinum rhodium alloy wire, reducing interference and making it more resistant to high temperatures.
2. The tray sensor is made of precious metal alloy wire and is finely crafted, with advantages such as high temperature resistance, oxidation resistance, and corrosion resistance.
3. Separate the power supply, circulating heat dissipation part from the main unit to reduce the impact of heat and vibration on the microcalorimeter.
4. The host adopts an isolated heating furnace to mitigate the thermal impact on the chassis and micro thermal balance.
5. The furnace body adopts double insulation for better linearity; The furnace body is equipped with automatic lifting, which can quickly cool down; With exhaust outlet, it can be used in conjunction with infrared and other technologies.
Controller and software advantages
1. Adopting imported ARM processors for faster sampling and processing speed.
2. Four channel sampling AD is used to collect TG signals and temperature T signals.
3. Heating control, using PID algorithm for precise control. Can be heated in multiple stages and kept at a constant temperature
4. The software and instrument use USB bidirectional communication, fully realizing remote operation. The instrument parameters can be set and the operation can be stopped through computer software.
5. 7-inch full-color 24 bit touch screen for a better human-machine interface. TG calibration can be achieved on the touch screen.
