DZ-TGA201 Thermal Gravimetric Analyzer RT+~ 1250 ℃

The working principle of thermogravimetric analyzer (TGA) is based on temperature programming, which measures the mass of a substance as a function of temperature or time. Its main components include a furnace, a balance, a temperature controller and a recording system.

Operating Principle

Heating process: The sample is placed in a crucible inside the furnace and heated or cooled at a certain rate by means of a programmed temperature control system. In this process, the sample undergoes a series of physical and chemical changes, such as water evaporation, organic decomposition, phase transition, etc., which can lead to a reduction in the mass of the sample.

Quality monitoring: The mass change of the sample is measured and recorded in real time by a high-precision balance. The balance converts the change in mass into an electrical signal, which is transmitted to the recording system, and finally shows the mass as a function of temperature or time in the form of a curve.

Data recording and analysis: The thermal stability, phase change temperature, decomposition temperature and other characteristics of the sample can be analyzed through the mass change curve recorded by the recording system.

Fields of application

It is widely used in research and development, process optimization and quality control in various fields such as plastics, rubber, coatings, catalysts, inorganic materials, metal materials and composite materials.

Structural advantages

1. The furnace body is heated by double-row winding of precious metal platinum rhodium alloy wire, which reduces interference and is more resistant to high temperature.

2. The pallet sensor is made of precious metal alloy wire, which has the advantages of high temperature resistance, oxidation resistance, corrosion resistance and so on.

3. The power supply, circulating heat dissipation part and the host are separated, reducing the influence of heat and vibration on the micro-thermal balance.

4. The main engine is used to isolate the thermal influence of the heating furnace on the chassis and the microthermal balance.

5. The furnace body adopts double insulation, and the linearity is better; The furnace body is automatically lifted and lowered, which can quickly cool down; With exhaust gas outlet, it can be used in conjunction with infrared

Controller, software advantages

1. Imported ARM processor, sampling speed, processing speed is faster.

2. Four-channel sampling AD collects TG signal and temperature T signal.

3. Heating control, using PID algorithm, precise control. It can be heated and kept constant in multiple stages

4. USB two-way communication is used between the software and the instrument, which fully realizes remote operation, and the parameter setting of the instrument and the operation stop of the instrument can be carried out through the computer software.

5. 7 inch full-color 24bit touch screen, better man-machine interface. The calibration of the TG is possible on the touch screen
