GA-S501 1500℃ STA Simultaneous Thermal Analyzer（Includes TGA+DSC function）

وصف

GA-S501 1500℃ STA Simultaneous Thermal Analyzer

Operating Principle

The operating principle of a simultaneous thermal analyzer (STA) is to measure the change in mass of a substance as a function of temperature or time, using programmed temperature control. Its main components include a heating furnace, a balance, a temperature controller, and a recording system.

A simultaneous thermal analyzer operates based on the temperature changes of a sample and the processes of heat conduction, absorption, and radiation. It controls the temperature of the furnace to heat, cool, and maintain a constant temperature for the sample, then monitors and records the sample’s temperature changes and the corresponding physicochemical properties.

Structural Advantages

1. The furnace heating system utilizes double-wound precious metal platinum-rhodium alloy wire to reduce interference and enhance high-temperature resistance.

2. The tray sensor is precision-crafted from precious metal alloy wire, offering high-temperature, oxidation, and corrosion resistance.

3. The power supply and heat dissipation circuits are separated from the main unit to minimize the impact of heat and vibration on the microthermobalance.

4. The main unit utilizes an insulated heating furnace to minimize the thermal impact on the chassis and microthermobalance.

5. The furnace utilizes double insulation for improved linearity; the furnace features automatic lift for rapid cooling; and an exhaust outlet allows for integration with infrared sensors.

Controller and Software Advantages:

1. Utilizes an imported ARM processor for faster sampling and processing speeds.

2. Four-channel sampling AD acquires TG and temperature signals.

3. Heating control utilizes a PID algorithm for precise control. Multi-stage heating and constant temperature control are possible.

4. USB bidirectional communication between the software and the instrument enables complete remote operation. Instrument parameters can be set and stopped via the computer software. 5. 7-inch full-color 24-bit touchscreen for an enhanced human-machine interface. TG calibration can be performed directly on the touchscreen.
